Usually I make matstsah using a cast iron skillet, but today I tried something new. I put the dough on a narrow grill grate, then I placed the grate directly over some hot coals inside of my wood-burning stove.
Strong's H4682 - מַצָּה (matstsah) n.f. unleavened bread, or cake(s) — unleavened bread, prepared in form of לֶחֶם (Bread); used at ordinary meals (prepared hastily); elsewhere at sacrificial meals, e.g. ritual peace-offerings; consecration of priesthood; at peace-offering of Nazirite; at Passover; esp. at feast of unleavened bread [cakes] for 7 days after Passover. During these seven days all Israel ate מצות (Flatbread)." ~ Brown Driver Briggs Hebrew Lexicon
