That’s just fine to wash in the d/w, then take them out and use them. I just put my jars/lids/rings in a stockpot of boiling water for 10 min., then remove them and do it that way; that way I don’t have to plan a d/w cycle.
As for whey:
quickie lemonade in a glass-water, a tablespoon of whey and about two tblsp. of lemon juice. I also add to smoothies where there is no other fermented dairy product. I also add a tablespoon to my cold tea.
use for soaking grains
use in lacto-fermenting veges
I give to the chickens on a hot, Ga. day.
