What is the primary purpose of using compound butter in a canapé?

The primary purpose of using compound butter in a canapé is to enhance flavor. Compound butter is made by mixing softened butter with various ingredients such as herbs, spices, or flavoring agents, which enrich the taste profile of the canapé. This blend not only adds depth and richness to the flavor but can also complement or contrast with the other ingredients used in the canapé.

While it can contribute to the visual appeal of a canapé, the distinctive taste that compound butter provides is its most significant role. It is also worth noting that while compound butter might have some effect on texture, such as possibly helping to maintain crispness in certain cases, its main function is flavor enhancement. Thus, the inclusion of compound butter results in a more appealing and flavorful product overall.
