I do know there are basically two kinds growing in the US both wild and domestic.make bread. It makes a beautiful color and a wonderful flavor bread. Wish I had some right now
I probably let mine go about a week....but never really keep a true schedule. I generally put 'em in one weekend and start using 'em by the next weekend. It's been quite a few years since I had a good haul. One of the neighbors used to grow them commercially - but he passed and the property has been sold.So freeze them first in the deep freeze? How long, a couple of days?
