Mix Masa Harina and 1 cup water in a bowl. Add remaining water, 1 tablespoon
at a time, until a smooth stiff dough is formed.
Scoop a lump of dough the size
of an egg into the palm of one hand. Pat it round and thin to 5 inches in diameter.
Or use a rolling pin, putting dough between two pieces of plastic wrap. The best
option is to use a tortilla press.
Have the griddle hot and cook one minute per
side until evenly light brown.
