Skirret harvest 2015

The other weekend I dug up my dormant skirret plants to harvest some delicious roots as well as divide the crowns.  Being Winter in Australia means that the skirret has died down and the roots are conveniently stored in the soil.  I have had a lot of people email me questions about skirret  (my email details are on my for sale page)so thought I should write another post about the harvest.
Dormant skirret plant
I wrote an earlier post on growing skirret from seed.  Skirret is a terrific perennial vegetable that desperately deserves someone to put in some dedicated breeding effort and bring it back into popularity.

Over the year the plants grew from tiny seeds into flowering size small plants, each year they will grow larger and stronger.  Unlike many perennial vegetables, skirret grew from seed, flowered and set more viable seed in a year, as well as that each plant produced a few offsets which can be divided and replanted.

The Skirret Harvest
To harvest I waited until they had finished flowering, then collected the seeds and store them safely, then I cut off the flower stalk and waited for the plants to die down.  The skirret eventually died down leaving nothing but some dead leaves to show where they had been, I then was busy and didnt do anything for a few weeks.  We eventually had some frosts, but I was still busy so did nothing with the skirret plants.  I am told like many winter vegetables that frost makes skirret sweeter and richer in taste, I have never eaten non-frosted skirret so can not comment on this.  Then when I had time I dug up the plants, removed the larger roots, divided the offsets, and replanted everything.

Upon digging the skirret plants I got to see how they had grown, they looked a lot like asparagus crowns.  Each plant grew a small handful of edible roots, the roots were only about 15cm long as this year were as thin as a pencil.  Being first year plants that is not too bad, older plants should grow longer and slightly thicker roots.  The plants were over crowded into a pot which was too small for one plant to grow well, which also would have lowered the yield.  I allowed the plants to flower and set seed, all of this takes a lot of energy and reduces the crop significantly.

What Does Skirret Taste Like
We did not get a large crop this year so I dug the roots, scrubbed the dirt off them, sliced them and ate them raw.  My kids loved skirret even more than I do, they could not get enough.

I forgot how much I like skirret, it tastes very sweet.  It is the sweetest thing that I grow, which is saying a lot considering I grow so many different fruit trees, herbs (including stevia the so called sweet herb") and vegetables (including yacon).  The skin tastes a lot like carrot, if scrubbed off you lose a lot of the carrot taste and are left with the sweetness.  It has another taste to it which I really like, I dont know how to describe it.  It is very mild and subtle, but it adds something nice to the sweetness.

How to store skirret
Skirret, like many winter root crops, stores best in the soil to be dug when it is needed.  It can also be stored well in the fridge in a plastic bag.  I have no idea if it can be frozen but I assume it can, if frozen I guess it would be no good for eating raw but should be good for cooking.  I have never tried freezing it myself, so you may need to use caution here.

I left some on the kitchen bench for a few days, it does not store well like this at all.  They lost their crispness very fast and became pretty inedible and droopy.  I did not want to lose any skirret as it is so delicious so I put those limp roots in a cup of water to see if they would rehydrate and become edible once again.  It appears that they do, they are not as good as the ones that were stored properly, but they are still nice to eat again.
Seed grown skirret, some are better than others
How To Grow Skirret
Skirret can be started from seeds, first year plants are smaller and often have a woody core.  Skirret grown from seed often exhibits a lot of genetic variability, this can be a great thing resulting in improved plants, or it can result in substandard plants.  They should all taste similar, but the yield will be different.  Seeds are tiny and do not have excellent germination, my fresh seeds are only showing about 70% germination and the tiny seedlings are inviting to slugs and snails.  Seeds are reasonably cheap and I am told that skirret seeds remain viable for about 10 years.  When buying a packet of 20 seeds it is not difficult to end up with well over a dozen plants which is more than most people will have room for.
Tiny skirret seedlings ready to be transplanted
The seeds are tiny, in spring I sprinkle the seeds on top of soil in a punnet and water them.  I wait until the seedlings have grown a bit before I plant them in their final spot as I find I can protect a punnet a bit easier.

Skirret offset ready to be planted
Most people who have the option grow skirret from offsets.  These offsets are essentially tiny cuttings that the plant makes itself, each one is genetically identical to the parent.  These tiny offsets sit dormant over winter, then when the time is right they start to grow and get a head start on seed grown plants.  They will grow a larger crop with less woody cores than first year seed grown plants.  Offsets are more expensive, and you get one plant per offset the first year.  Each year after that your skirret will divide and flower.

I plant the offsets so that the growing tip is just beneath the soil surface, if you get heavy frost you way want to plant them a bit deeper or mulch the tiny offset over winter.  If you live somewhere without frost you can plant the offset so that the tip of the leaves are just poking out of the soil.  You will need to protect them from slugs and snails while they are little.  The offsets are pretty small, they usually will have no roots at this stage, this is normal and they will grow well from this when the weather is right.
Skirret offsets, they are small but they all will grow
Where to buy skirret in Australia
I sell packets of skirret seeds, they are a great way to grow a decent number of skirret plants.  I also sell offsets or small plants from my better plants on my for sale page, they are a great way to grow known performing plants that should grow larger than from seed reasonably fast.  I only sell offsets from the better plants.

I will sell offsets over winter, but they will be dormant and not do much until spring, if I have any left I plan to sell small plants over the warmer months.  Above is a picture of some skirret offsets next to a measuring tape for scale so that you can tell exactly what you will get if you buy them.

The Toxicologist is cooking poison

I am preparing two HUGE articles to be posted pretty soon on The Toxicologist Today. Two articles that
promise excitement, passion, opinionated criticism, critical analysis, appraisal and  possible - yet uncalled for - controversy at points. 

Right now I can only give you a few ideas surrounding these articles I have been taking some time to write:

1 - Is LinkedIn becoming another Facebook?

2 - I am recruiting... an Employer.

I really hope this gets you guys, psyched! Hope I can count on your visit soon.

Cheers.

Top Recent and Outstanding Portuguese Scientific and Technological Achievements

I am here celebrating Portugal, for today 10th of June 2015, is Portugal Day. And for those who think we dont mean science youre so wrong. We are clever, we have always been astute and quite ingenious under very difficult economical conditions. From Braamcamp (inventor of the brick in 1853 - top image) to Patricio Vieira da Silva (inventor of the anticonvulsant Eslicarbazepine acetate in 2014), the world has gained from the Portuguese ingenuity and creativity. Check hereby our recent top contributions to the world of science and technology and vote/comment on the one you believe is the most impressive achievement for such a small nation as the Portuguese Republic:


ENDOSCOPY, 1965, by Fernando Alves Martins
Endoscopy means looking inside and typically refers to looking inside the body for medical reasons using an endoscope, an instrument used to examine the interior of a hollow organ or cavity of the body. Unlike most other medical imaging devices, endoscopes are inserted directly into the organ. 



BIGGUN – CHILD & ACCIDENT PROOF ROTATING PERCUSSION HANDGUN, 2004, by Fernando Lopes
RPH – BIGGUN - The first Less-Than-Lethal (LTL) weapon concept to be demonstrably created in Portugal and in the XXI Century, with the main purposes of saving Human Lives. It brings various defence and safety mechanisms, which combines a high level of defence and effective protection by virtue of its unique characteristics with the advantage of providing greater safety, in order to go some way towards reducing the high firearms accident rate among adults and children. Considered the “World’s Safest Weapon”. 



PROCESS FOR THE PREPARATION, UNDER SUBCRITICAL CONDITIONS OF MONOLITHIC XEROGELS AND AEROGELS OF SILICA/LATEX HIBRIFS, MODIFIED WITH AKOXYSILANE GROUPS (SPACE SHUTTLE SHIELDS - AEROGEL ), 2006, by Instituto Superior Tecnico
The invention relates to a process for the preparation of monolithic xerogels and aerogels of silica/latex hybrids under subcritical conditions. In the two-stage synthesis of these alcogels in the presence of an acid-base catalyst, the hydrolysis and polycondensation of a silicon alkoxide are carried out in an organic medium containing excess water. A latex consisting of polybutyl methacrylate and polybutyl acrylate, modified with alkoxysilane groups, is first synthesized and then incorporated in the mixture either in the first stage in order to effect its co-hydrolysis with the silicon alkoxide, or in the second stage to effect its cocondensation with the previously hydrolysed colloidal silica. The resulting alcogels are aged, washed, and dried under subcritical conditions. 


ESLICARBAZEPINE ACETATE AND METHODS OF USE, 2014, by Patricio Soares da Silva
New applications of eslicarbazepine and eslicarbazepine acetate in the treatment of intractable conditions, selected from epilepsy, central and peripheric nervous system disorders, affective disorders, schizoaffective disorders, bipolar disorders, attention disorders, anxiety disorders, neurophatic pain and neuropathic pain-related disorders, sensorimotor disorders, vestibular disorders, and nervous function alterations in degenerative and post-ischemic diseases. 

The Multibanco System
Portugals Multibanco System is a sophisticated system of Automatic Teller Machines (ATM). SIBS (Sociedade Interbancária de Serviços SA), the company behind Multibanco, launched the network in September 1985 with the installation of 12 machines in Lisbon and Oporto. Over 11,000 machines are now available throughout Portugal, in banks, supermarkets, shopping malls, stations, museums and airports.
  • The SIBS website has information about the Multibanco services, useful information and news in English: Click here
Prepaid Mobile Phone
A prepaid mobile phone (also commonly referred to as pay-as-you-go, pay-as-you-talk, pay and go, prepaid wireless, prepay or, if soon disposed of burner phone) is a mobile phone for which credit is purchased in advance of service use. The purchased credit is used to pay for mobile phone services at the point the service is accessed or consumed. If there is no available credit then access to the requested service is denied by the mobile phone network. Users are able to top up their credit at any time using a variety of payment mechanisms. The first European PAYG deployment was in Portugal in 1995 when Portuguese operator TMN deployed a PAYG solution called MIMO.

All-on-four dental method
Developed in the 1990s by famed dentist, inventor and businessman Paulo Maló, in collaboration with a Swiss prosthetics company called Nobel Biocare, the All-on-Four procedure quickly came to be recognized as one of the biggest breakthroughs in modern dentistry. Because the arches are replaced all at once – anchored to the jaw using four titanium screws – the procedure is faster, less invasive and less expensive than the alternative of replacing each and every tooth with its own dental implant.

Via Verde
Via Verde (literally "Green Lane") is an electronic toll collection system used in Portugal since 1991. It is available at all toll roads and bridges in the country since 1995. Toll roads and bridges are operated by multiple operators, the main being Brisa - Auto-estradas de Portugal. Upon passing in a non-stop lane at a toll, a DSRC tag attached to the vehicles windshield transmits its identifier and the toll amount is debited directly from the clients bank account. If an exception is detected (the tag is invalid (or non-existent) or the vehicles class (as detected by the lane sensors) does not correspond to the class encoded in the tag, amongst others) the vehicle is photographed and, if there is indication of fraud, a legal procedure is initiated.

See you back in July. Go on and read other posts while  The Toxicologist Today is on holidays. Cheers!

Bruno caught in the act
Its finally breeding time around here.  Three weeks ago we bred our two American Blue rabbits for the first time. If all goes as planned, with a gestation period of 28 days it looks like we only have a few more days to wait for little bunnies.  I just finished making, larger more comfortable quarters for the ladies. 


And even more exciting, the bucks have arrived!  Welcome to the boys, our guests for a month, from Green Faerie Farm in Berkeley.  Ellis and Bruno are pure bred Oberhasli, a very old dairy breed originating in Switzerland, also known as Swiss Alpine.  Oberhaslis tend to be quiet, sweet natured and hardy, have high milk production, and are fairly rare in the U.S.  Only six months old but fully equipped with the right parts,  they sure have been entertaining us all with their hilarious antics.  And whats all the hoopla Ive always heard about how stinky the billies can be?  These guys are actually pretty mild smelling.  Dare I say, their scent is almost reminiscent of patchouli.  Did I also mention how adorable they are...it wont be easy letting go of these two in a month.   Gestation for a goat is five months and their heat cycle is every three weeks.  We originally planned to breed only Bella and Rosemary, but since the boys are here and good breeding stock is hard to come by, we may go ahead and breed all four of our ladies.   After observing the herd for a few minutes its clear that Bella and Rosemary have been waiting for some male attention their whole lives!

Small mistakes

I just been to the 1st International Symposium on Quorum Sensing Inhibition in Santiago de
Compostela, Spain. Let me tell you those guys know how to throw a Symposium. It was pretty impressive. Great speakers, great presentations, great history all over the city centre, super interesting subjects, my poster, nice funny audience, all great.

And whilst checking the registration list looking for some Portuguese fellows for exchanging a few ideas on the state of the country in terms of science and research, I managed to find some really odd surnames. Thats when I commented with a few friends from Nottingham that these Portuguese surnames werent very Portuguese at all (just like mine, Lafayette!!!). But one really caught my attention, Smallmatek. And I asked my fellow mates "Who the hell calls himself Smallmatek?" when in between crazy laughter they replied "Mate, thats their company name".

Oooooppps. 

Fair enough, at least the company "Smallmatek" is Portuguese, I wasnt that wrong, heheh!

Anyway, today is Portugal Day and I had to remember our impressive contribution to science in a post to come today!
