Found this reference on another website: Tubers are difficult to store because of the thin skin which permits shrinkage and injury that leads to decay. They keep perfectly if left in the soil until needed, freezing does no damage. Although they cannot be harvested from frozen soil, tubers for spring planting are best left in place until spring. They should then be harvested and handled promptly before they sprout appreciably. Tubers should not be left in poorly drained soil. Good, sound, diseasefree tubers can be successfully kept several months in cold storage at a high humidity and a temperature of 0°C.

These are so so yummy! I scrub wash under running water, boil them in salted water, or steam them, they don't need a long time cooking, so do test before you strain them. I then chop finally continental parsley and garlic, sprinkle this over J A drizzle olive oil salt and pepper, and this is a great dish to have with canned tuna, olives etc etc..Oh...the gas comes free :)

I got a lot from my grandfather one year but made the mistake of dishing them up to a group of friends just before we went to see a play..... those who have eaten them before can imagine the consequences. Really yummy, but unfortunately they do have a side effect not compatible with a quiet live theatre.

Today I bought a net of JA tubers to plant at Bunnungs. $12 for 8. I asked about 8 weeks ago and they weren't avail. Are now, though! (23/7/11)
