I want to deep fry some pickles, but I want to have them ready ahead of time. The coating I like is a sort of cornmeal buttermilk batter. How can I freeze these without it all coming off?
I am assuming you mean freeze after frying. The bad news is that there is probably no foolproof way of retaining the crispness of fresh-fried pickles through freezing. A few tips to prevent them from being limp/soggy:
After frying, please make sure each of them are cooled out in open air (like in a cooling rack on baking sheet etc) instead of a locked container and/or stacked on top of each other. This prevents them from being all soggy from the slow-releasing steam.
You need to thaw them/slightly bake them in a oven to bring back some of the crispiness. Microwave thawing will turn them mushy.
