Makes 8, ~1hr.
250g plain flour
1.5 tsp baking powder
1 tsp salt
2 tsp vegetable oil
180 ml warm water
Sift together the flour, baking powder and salt in a bowl. In another bowl combine the warm water and oil. Add the water/oil mixture to the flour mixture, one tablespoon at a time and mix until all the water is mixed into the dough.
Lightly flour a wooden cutting board and knead the dough for ~5 minutes until smooth. Place the dough into a clean bowl and cover with a damp towel. Let the dough rest for 20 minutes.
Divide the dough into golf-ball-size balls. Place the balls on a flat dish making sure they don't touch each other and cover with the damp cloth. Let the dough rest again for 10 minutes.
Lightly dust your wooden cutting board with flour. Take one of the balls of dough and flatten it. Roll the tortilla until it is 6 or 7 inches in diameter and about 1/8 inch thick. Once you have rolled out the tortilla, place it on a preheated skillet (medium/high). You don't need to add any oil or butter. Cook the tortilla for about 30 seconds. You will notice brown spots all over your tortilla. Flip it over and cook an additional 30 seconds. Repeat for the remaining dough balls.
