Relishes typically contain cooked and pickled vegetables; the one here is mouth-tinglingly tangy. James Syhabout of Oakland, California's Commis makes it by pickling shallots, capers, pistachios and pink peppercorns overnight in Champagne vinegar and olive oil. It's awesome on tomatoes, but he also likes using it on fish.
