Whisk together flour, salt, baking powder, and sugar in a bowl.

Add milk and eggs to the dry ingredients and mix well with a whisk.

If making plain pancakes, add vanilla yogurt and mix well.

If adding fruit, omit the yogurt.

Add thinly sliced or grated apple (or peach) to the batter and mix well.

Let the batter rest for 20 minutes.

Heat oil in a pan or griddle over medium-high heat.

Spoon heaping tablespoons of batter onto the hot surface.

Fry until bubbles appear on top and some burst.

Flip the pancakes and fry for approximately one more minute, or until golden brown.

Remove pancakes and place on a paper towel-lined plate to drain excess oil.

Serve warm, garnished with powdered sugar.
