Step 1

Combine the all purpose and corn flour. Mix in the salt and baking powder, set aside. In a large bowl, add the shortening(or lard). Heat in the microwave, just until it melts, about 45 seconds. Stir in the annatto powder(if using). Mix in the 2 cups of hot water.

Step 2

Gradually add the dry ingredients into the wet, little at a time and stirring well to mix as you go. When the dough comes together, transfer to a flat work surface. If if feels a little dry, add the remaining 2 tablespoons of water. Knead the dough well for 3 to 5 minutes. Divide the dough into 30 balls. I usually tear just enough dough that fits comfortably in the palm of my hand, about the size of a golf ball. If you want bigger tortillas, then you can tear off a little more. Place dough pieces in a plastic bag, spread out, and let them rest for 1 hour.

Step 3

After and hour, preheat your comal(griddle) to medium heat for 5 minutes. Roll  dough into a smooth ball and flatten slightly. Place on flat surface and roll out one tortilla, adding as little flour as possible, to about 4 1/2 to 5 inches in diameter.  This dough rolls out much easier the the all flour tortilla. Apply gently pressure as you roll and turn(or flip) as needed to achieve a circle.

Step 4

Test the first tortilla to see if comal is at a good temperature.  Tortilla should begin to bubble slightly a few seconds after you place it on comal.  Once you see many bubbles or one big bubble, turn the tortilla and cook for another 30 seconds. If the temperature is good, you should see brown spots, all sizes on the tortilla. If the spots get dark too fast, your comal is a little too hot.

Step 5

Place tortillas in between a large kitchen towel, spread out, as you cook them. Once done, flip all the tortillas, cover again. Let them cool covered at room temperature. Once cooled, store in a plastic storage bag on the counter for a few days. If not using right away, place in refrigerator for 7-8 days. Reheat on preheated comal for just  a minute, turning as needed. Keep in a tortilla warmer.
