Crème de Noyaux

A 19th century French liqueur, Crème de Noyaux is made from infusing a base spirit with the kernels from apricot, peach and/or cherry pits, then adding simple syrup. It was traditionally dyed pink with carmine, a natural dye made by grinding up cochineal insects. It is hard to find these days, but Tempus Fugit makes an excellent version.
