Biscuits you can’t eat? If you are talking about woodworking, this is true. If a woodworker wants to closely join two pieces of wood, he will use “wood biscuits” to do so. They are discs that are cut thinly to fit into a groove on each of the pieces to be joined. Using glue alone to join the boards or pieces would not give enough strength. Wooden pegs or dowels used to be used, but biscuits are stronger and easier to use, especially if you use a biscuit joiner. The biscuit joiner cuts the grooves in each side of the wood; the biscuit is covered with glue and inserted in the grooves, giving a strong joint.
