Chive Blossom Butter. When chive blossoms are in bloom, this is one of my favorite ways to preserve their delicate onion flavor and beautiful purple color. Spread it on warm bread, melt it over grilled steak, toss with vegetables, or add a pat to baked potatoes. Best of all, it freezes beautifully, so you can enjoy a taste of spring long after the blossoms have faded.
