Define "biscuit joinery."

Biscuit joinery refers to a method used in woodworking where a wooden biscuit, which is an oval-shaped piece of compressed wood, is used to connect two pieces of wood. This process involves cutting matching slots in both pieces of wood, where the biscuit is inserted along with glue. When the glue dries, it creates a strong joint, providing stability and alignment to the pieces being joined. This technique is especially useful for edge-to-edge joining, as well as in creating sturdy corners and other connections in furniture making.

While other options may touch upon various aspects of woodworking, they do not accurately describe the specifics of biscuit joinery. The focus on the wooden biscuit as a connecting element is what defines this technique uniquely in carpentry.
