These traditional quick-pickled Brussels sprouts are a tangy and crunchy side dish that pairs perfectly with any meal. The Brussels sprouts are blanched to retain their vibrant green color and then pickled in a mixture of vinegar, sugar, and spices. The result is a deliciously tangy and slightly sweet flavor that complements the natural bitterness of the Brussels sprouts. Serve these pickled Brussels sprouts as a side dish or add them to salads and sandwiches for an extra burst of flavor.
