Combine all the Ingredients: In a large bowl, mix all the ingredients, such as baking powder, salt, and all-purpose flour. It is best to use your clean hands to mix all the ingredients thoroughly after adding the shortening.
Add Warm Water: Slowly pour the warm water and mix until a smooth and desired consistency is obtained for making a soft dough. Cover it with a clean towel, napkin, plastic, or cloth and let it be at least 10-15 minutes. This extra time of setting will allow the gluten to develop and make it easier to roll out and form sopapilla.
Divide the Dough: Cut the soft dough into a small-sized round ball. Try to roll out every ball into oval-shaped balls, almost ⅛ inch in size. If you prefer, you can make square-shaped sopapillas too; by the way, I like the oval shape more.
Fry the Sopapilla: Heavy a large pan on low-medium heat and add vegetable oil for frying. Fry all the sopapillas one by one; remember, do not add all of them at a time. If you do so, they can be burned, or don’t fry thoroughly.
When turning golden brown, turn the side and repeat the process with all the sopapilla balls. It takes approximately 1-2 minutes to fry each side. To withdraw all the extra oil from them, put them on absorbing paper.
Put them in a Microwave: To keep them warm and fresh while frying the sopapillas, keep them in the low-temperature microwave until ready to eat.
