Before you measure the flour, sift or stir it to remove any lumps and remove compaction for accurate measuring.
In a large bowl, mix together the flour, baking powder, and salt.
Add the butter or lard, or a combo to the flour mixture and combine until the pieces of fat are small. Use a fork or pastry blender, I use my fingers. Sprinkle the apple cider vinegar over the flour.
Gradually add the hot water while stirring. I use my hands, but you could use a spoon. The dough will be wet and sticky.
Knead in the bowl for about 3 minutes. The dough will be sticky at first but will soon stop sticking to your hands. This is an important step.
Divide the dough into the required number of portions. Depending on the size you wish for your tortillas, divide the dough into 8 (for larger burritos), 10 (medium-size), or 12 (small) evenly sized balls.
Place the balls back into the bowl and cover it with a damp towel. Let the dough balls rest for 10 minutes. This step is crucial.
Flour your rolling surface and rolling pin (my favorite rollling pin) lightly. Roll the dough balls into a circle shape until they are translucent when held up to the light (I never get perfect circles).I drape the tortillas over the side of my bowl once I’ve rolled them. Once you have rolled two tortillas, start preheating your cast iron griddle, or griddle of your choice, on medium-high heat.You'll know it's hot enough when drops of water dance across it and evaporate. It should take about 3 minutes to be properly preheated.
