In a bowl combine the flour, oil, salt and baking powder.
Add in the hot water, slowly and not all at once. Mix together with a fork to start then start, then once it's not too hot to touch, gently knead by hand until it forms a soft but not sticky, pliable dough. You may not need all the water, especially when adding other wet ingredients like spinach or beetroot.
Leave this dough to sit and cool for 5-10 minutes.
Place the dough ball on a floured bench and cut into 6-8 even sized pieces.
Preheat a pan to medium-high heat. I like to use a cast-iron pan.
Roll one piece of dough out into a circle of about 1.5mm thickness.
Place in the preheated pan, don’t add any grease or oil. If the dough starts smoking, turn down the heat.
Cook on one side for two minutes before flipping and cooking on the other side for 1.5 minutes more.
Repeat the rolling and cooking process with the remaining dough. Place the cooked tortillas on a wire rack or plate to cool, stacking them on top of each other. Cool completely before rolling up.
