Brought in a new haul today for my silkworms, hopefully this keeps them full till they caccoon out. Here are a few pictures I took to of blanching process. I get a large pot to a rolling boil and put in a handful of leaves at a time for 90 seconds. I then immediately place them in a cold water bath, to stop the cooking. Then a quick dry and a trip to the freezer. I find that if you don't place them in an ice bath after boiling, they get soggy after you thaw them for future use.
