Compound butter is a mixture of softened butter and various flavoring ingredients, such as herbs, spices, garlic, or citrus zest. It is often used to enhance the taste of meats, vegetables, and bread. By blending these ingredients into the butter, you create a versatile condiment that can be easily spread or melted over dishes. This flavorful butter can be made in advance and stored in the refrigerator or freezer. When ready to use, simply slice off a piece and let it melt over your favorite foods, adding a rich and aromatic touch to your meals.
