Today I had some small heads of broccoli to preserve. So the tops went in to be blanched but I had heard that you could use the stems as well.
So I peeled them with a carrot peeler and cut them in rounds and blanched them. Then I put them in the dehydrator. You are supposed to dry them and then grind them up in your food processor to make broccoli powder which is good in dips and soups. Sounds like a fine idea to me. Less waste the better.
