I love pickled foods and at any given time homemade quick pickles are in my fridge. From pickled red onion, pickled yellow mustard seed, pickled cauliflower, red pepper, ginger, almost anything that is season at the Farmer's Market or in surplus in the home garden is preserved as a quick pickle. They are so handy for jazzing up a salad or sandwich or cold plate lunch or main dinner plate and serve as an impetus to using them in unusual ways because I really dislike to waste things....thus the pickle in the first place.
I refer to Sean Brock Heritage and Einat Admony Balaboosta cookbooks for some of my ideas for spicing.
A pickle plate appetizer at Graze, Tory Miller's gastropub in Madison, Wisconsin several years ago was a revelation. Perfectly harmonious yet in different brines and seasonings asparagus, rhubarb, ramps got me started on the pickle passion.
