Pickled mustard seeds are a tangy and flavorful condiment that adds a burst of flavor to any dish. Made by simmering mustard seeds in a mixture of vinegar, sugar, and spices, these tiny seeds become soft and plump with a slightly sweet and sour taste. They are perfect for adding to sandwiches, salads, or charcuterie boards. The pickled mustard seeds can also be used as a garnish for meats or roasted vegetables, adding a pop of color and flavor to your dishes.
