Mix the flours and salt together in a bowl. Add the shortening/butter/lard in small pieces and crumble it into the flour with your hands until it's sandy.

Slowly add the water and mix with hands until the dough comes together enough that you can shape it into a ball without it falling apart.

Remove the dough ball onto a floured surface and knead with the palm of your hand until it's soft and smooth, 5-10 minutes.

Divide the dough into 12 equal pieces and roll each piece into a small ball.

Return the balls to the bowl and cover with a clean, moist cloth or plastic wrap. Let rest for 30 minutes.

Heat a flat frying pan or griddle on medium (without oil). When hot, form a ball into a flat, round shape with your fingers (about 4 inches round and 2~3 mm thick).

Put it into the hot pan and cook on one side until you see little bubbles and the bottom is lightly browned (about 1-2 minutes).

Flip over and lightly brown the other side for about 30 seconds to 1 minute. Don't over cook or they will get stiff!

Remove the cooked tortilla onto plate covered with a clean tea towel or cloth, and cover the tortilla with the cloth to keep warm and moist.

Repeat with the process with the rest of the dough balls until all are cooked. Stuff with your favorite fillings and enjoy!
