Put the eggs, milk, salt and sugar in a bowl then mix everything together until you see bubbles on the surface.
Mix the baking powder with a few drops of white vinegar or lemon juice then add it to the eggs.
Put the flour on top of the eggs and mix everything together.
When the flour and eggs are mixed together, put a frypan with a little bit of oil on a low heat. I use a teaspoon to add the oil after each pancake to be sure I don't use a lot. When the frypan is hot, add from the egg mixture until the bottom of the frypan is covered.
When the pancake starts coming off the edges of the frypan it's time to turn it over. After it's done put it on a plate and spread a tablespoon of jam on it. Roll the pancake or fold it in four.
