4 cups all-purpose flour
1 teaspoon salt
2 teaspoons baking powder
2 tablespoons shortening or lard
1 1/2 cups hot water

Whisk the flour, salt, and baking powder together in a mixing bowl. 
Mix in the lard with your fingers until the flour resembles cornmeal. 
Add the water and mix until the dough comes together; place on a lightly floured
surface and knead a few minutes until smooth and elastic. 
Divide the dough into 24 equal pieces and roll each piece into a ball.

Preheat a large skillet over medium-high heat. Use a well-floured rolling pin to
roll a dough ball into a thin, round tortilla. Place into the hot skillet, and
cook until bubbly and golden; flip and continue cooking until golden on the 
other side. Place the cooked tortilla in a tortilla warmer; continue rolling and 
cooking the remaining dough.

Makes about 16.
