Authentic Navajo Indian Fry Bread (Taco Bread)

2 cups oil (for frying)
4 cups all-purpose flour
3 tablespoons baking powder
2 tablespoons salt
2 1/2 cups warm milk (more or less)

In a heavy large frying pan heat the oil to 365 degrees; Oil is hot enough if a small test piece of dough dropped in the oil begins cooking almost immediately and rises to the top. Mix together dry ingredients in a large bowl; *see note about salt. Gradually add warm milk and mix to make a soft dough. When the dough has pulled together, cover and let sit in a warm place for 10 to 15 minutes. Break off a golf ball sized piece of dough and pat it out flat in your hand, no thicker than 1/4 inch. Place 2 or 3 flats at a time into the hot oil and when they begin to bubble flip them over and fry until they're a nice light golden brown. Remove and drain on paper towels then serve hot (keep them covered in a bowl until you're done frying). You can make larger flats; just make sure they're no thicker than 1/4" and fry one at a time.
