what is the least amount of time that this step can be done? is over night mandatory? if so why? thanks!
I make & freeze pesto all the time. Put in ice cube trays, when frozen, store in freezer bag. I throw a "cube" or 2 in homemade soups (especially chicken) and stews. Yum!
Thanks Mrathmel...I am not sure what happened here! I was looking for an answer to one of the recipes I am testing about pancake batter! I too do exactly the same as you with pesto in the freezer! :)
