Bacon-Fat Flour Tortillas

Preparation

1. Step 1

   Cook bacon in a large broilerproof skillet, preferably cast iron, over medium heat, turning occasionally, until brown and crisp, 8–10 minutes. Using tongs, transfer bacon to a small bowl and save for taco filling. Pour off 2 Tbsp. bacon fat from skillet; set aside for making tortillas. Set skillet with remaining fat aside for making taco filling.

   Step 2

   Bring oil, 3/4 cup milk, and reserved 2 Tbsp. bacon fat to a simmer in a small saucepan (be careful not to boil); immediately remove from heat. Whisk baking powder, salt, and 3 cups flour in a medium bowl to combine. Pour in hot milk mixture and remaining 1/2 cup milk. Mix with your hands until a shaggy dough forms.

   Step 3

   Turn dough out onto a lightly floured work surface and knead until smooth and elastic, about 4 minutes. Wrap in plastic and let rest at room temperature 1 hour to relax dough.

   Step 4

   Divide dough into 16 Ping-Pong–size balls (about 1 1/2"). Working one at a time and keeping remaining balls covered with a kitchen towel, roll out on a lightly floured surface to 6" rounds.

   Step 5

   Heat a comal, griddle, or a clean large cast-iron skillet over medium. Working in batches, cook tortillas, reducing heat if they are getting dark too quickly, until brown in spots on bottom sides and air bubbles form on surface, about 2 minutes. Poke large bubbles with a fork to release steam, flip tortillas, and cook until brown in spots on second sides, 1–2 minutes. Stack and wrap tortillas in a kitchen towel as you go. This will keep them warm until you are ready to assemble your tacos.
