Place the eggs and milk in a bowl. Then add the olive oil/butter (butter will give a thicker consistency)

Separately in another bowl place the flour, salt and sugar. Then add to the dry mixture about 1 cup of the liquid and mix.

Add the rest of the liquid and mix to form a smooth, watery batter.

Cooking: after lining the pan with butter use 1/4 cup of the batter into the hot pan. Spread the batter and fill making sure it is spread evenly and thin.
