Medieval Castellanization of the Latin expression ad torrendum, to cook under the ash or to twist the bread acimo, without yeast, which they also called sub-incineration or bread to torquendo of Hispanic Jews, of torque, to spin, to turn, to turn. The bread to tower or torquendo resulted in a flattened round cake as there was no fermentation. From here the Christian saying "in the absence of bread, good are cakes".
