3 tablespoons plain four
3 tablespoons milk
Mix the egg and flour and gradually add the milk a bit at a time while whisking.
Heat a little oil/butter in a pan and add a table spoon of the batter. Cook on one side till little bubbles appear on top (a minute or 2) then flip to cook the other side.
I have added grated cheese to the mix which was nice, also 1/2 a mashed banana and some blueberries. You could try adding anything really!
I also added 1/2 teaspoon of baking powder which made them a bit fluffier.
