Leeks are a traditional fall vegetable (they can be harvested even after a frost), perfect for making rich soups and stews, adding to roasted vegetables, or garnishing main dishes and salads. With a mild, onion-y flavor and beautiful texture, leeks add variety to any meal. Be sure to keep them refrigerated, and use them promptly. Another key to enjoying leeks is to wash them thoroughly. Find Maine-grown leeks at farm stands, farmers’ markets, and local stores starting in late August.
