The baking of matzah is labour-intensive, as less than 18 minutes is permitted between the mixing of flour and water to the conclusion of baking and removal from the oven. Consequently, only a small number of matzot can be baked at one time, and the group members are enjoined to work the dough constantly so that it is not allowed to ferment and rise. A special cutting tool is run over the dough just before baking to prick any bubbles which might make the matza puff up; this creates the familiar dotted holes in the matzah.
