Leach (food)
Leach was a popular medieval sweetmeat consisting of a thick, jelly-like preserve which set hard enough to be sliced for serving.
They consisted of sugar and flavourings such as almonds, dates, dried fruit, peel and fruit extracts, sometimes spiced or with milk added, and thickened with isinglass or gum arabic.
Leaches were often shaped or moulded into fancy shapes such as hearts, diamonds, clubs, spades, or crescent moons. They would feature as a decorative display on a silver tray at the dessert course of banquets, where specialised sweetmeat spoons with a fork at the handle end might be provided. They were also eaten through the day, perhaps as a breath freshener, and were a favourite of Elizabeth I.
