Thoroughly combine the flour, baking powder, and salt in a medium sized mixing bowl.
Add the butter and hot water, then mix until a shaggy dough forms
Work the dough until smooth, but don't overwork it.
Warm your skillet on medium/high while you roll the dough. Dump the dough onto a floured surface and divide it into 8 equal sections (or 6 for smaller tortillas)
One by one, roll each section into a ball and then use a rolling pin to roll it out to a paper thin circle, keeping the surface floured to avoid sticking.
You can roll them all out before cooking, or cook as you go to save time. Once you are ready to cook, just place the flattened tortilla on the skillet and let it cook until bubbles form. about 5-10 seconds. Don't burn it!
Flip it over and cook the other side.
Place the cooked tortillas in a tortilla warmer or on a cloth-lined plate to keep nice and warm.
They are divine right off the griddle, but you can serve these soon after cooking or store them for later. Storage instructions are listed in the post above.
