Preheat oven to 200°C. Put flour into a bowl and add the eggs. Beat well and start to add milk in small amounts. Keep beating to ensure that there are no lumps. Season with salt.
Preheat 1 teaspoon of oil per individual pudding in the tin until searing hot (5 mins should do it). Then pour in the batter and quickly return to the oven. Bake for 15-20 mins until golden brown and crisp on the edges.
Great served with sausages for little individual toad in the hole!
