Each Showbread loaf was made of two "esronim" of fine wheat flour and water. This bread was unleavened. The loaves were each kneaded separately. They were then baked in pairs in the oven. Each loaf was placed in a pan called the "defus," which was a special mold. This mold preserved the unique shape of the loaves, described by the sages as being similar to "an open box." Its dimensions were ten handbreadths in length by 5 handbreadths in width before being folded. (Source:Menahot 11.)
