Where can one find the recipe for challah bread?

Matza meal is not like cake meal - for making a cake. Matza meal is ground up matza so that you can bake with it. It can sometimes be used in the place of flour to make cakes, cookies etc but you can not always substitute for flour as the properties are very different. Flour is used to make matza, it is mixed with water and baked quickly. I wouldn't make your own Matza, as the laws of rising can be complicated.
