Renaissance leach recipes were very popular in the 1600s. Don't worry, I'm referring to "leaches" the jelly-like sweetmeat... NOT the wriggling "leeches" that swim — BIG difference!
Leach was a common medieval confection consisting of a thick, jelly-like preserve set hard enough to slice for serving. Leaches were often shaped or molded into fancy, traditional shapes such as hearts, diamonds, cubs, spades, or crescent moons. This made them very decorative when displayed on a fine, silver tray at banquets.
The chewy sweetmeat was often made using almonds and various natural fruit flavorings. Some leaches were like fruit leathers, and some might have been similar to today's popular gummy worm candies in chewiness and texture.
