Golden Rutabaga-Onion Pickle

Quick to prepare with a food processor, this wonderfully crunchy refrigerator pickle is hard to identify but easy to fit into a meal. Refresh a leftover roast with the pink and gold slices, or add a tart snap to seafood, grain, or starchy salads (especially ones with avocado, an ideal match). For variety, add chillis, anise, or caraway to the pickling liquid. For more brilliant color, add a thin-sliced raw small beet.
