The process of pickling keeps just about anything from decaying over time, preserving specimens for scientific study and textbooks for use in future meals. Imbibe edible notes with today’s Groupon: for $5, you get $10 worth of pickled fare at The Pickle Guys’ Brooklyn location.

Owner and brine master Alan Kaufman reignites the tradition of classic barrel pickling by curing a variety of pickled fare in casks without preservatives, soaking the snacks for up to six months before dishing them out by the quart, half gallon, or gallon. More than 30 types of brine-soaked morsels line the shelves, including the classic new pickles, sour pickles, and hot new pickles (all $6.25/qt.). Other vinegar-soaked veggies run the gamut from sliced hot peppers ($10/qt.) to marinated mushrooms ($14.50/qt.), remedying sodium deficiencies and the architectural instability of the food pyramid. Pickle Guys also jars seasonal creations, such as pickled pineapple ($11.50/qt.).
