In a food processor, add the flour first along with the baking powder, sea salt, and lard. You must do this before adding the water.
Add the water in slowly after all the dry ingredients have been put in and blended.
Remove the dough from the food processor and knead the dough.
Let the dough sit for at least 20 minutes. Sometimes it is best if you let it sit in the fridge overnight wrapped in saran wrap.
Measure out 1.5 ounces for each tortilla.
Use a tortilla press for best results or roll out.
Warm cast iron skillet. Place the tortilla on the iron skillet for a minute or two on each side or till the tortilla starts to rise and then place it in a covered basket to the side.
