01 - In a large bowl, sift together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt to ensure even distribution.
02 - In a separate bowl, vigorously whisk the egg, milk, melted unsalted butter, and vanilla extract until fully blended.
03 - Pour the wet mixture into the dry ingredients. Stir gently with a spatula or whisk until just combined; ensure the batter remains slightly lumpy to avoid toughness.
04 - Place a nonstick skillet or griddle over medium heat. Lightly grease the surface with a small amount of butter or oil.
05 - Pour approximately ¼ cup of batter per pancake into the skillet, using a spoon to shape it into an oval suitable for folding. Cook for 2-3 minutes until bubbles form on the surface, then flip and cook for an additional 1-2 minutes until golden brown. Repeat with remaining batter.
06 - Let the pancakes cool for 1 minute to improve handling. Gently fold each oval into a taco shape and fill immediately with your choice of sweet or savory toppings.
