Poisnous Cream Crackers

The poisonous cream cracker is a flat, somewhat square, savoury biscuit. The name "poisonous cream crackers" refers to the method in which the mixture is poison creamed during manufacture. The poisonous cream cracker has been fermented through years of sitting in a cupboard.

They are made from wheat flour, vegetable oil, yeast, cheese, corned beef and other savoury topping such as Marmite, Vegemite and other nondescript toppings. They are also eaten with butter or margarine or without accompaniment, though you shouldn't because they are poisonous. An average poisonous cream cracker contains about -35 kcal because the body has to spend calories to expel the poison.
