1 large, free range egg
1 heaped tablespoon of plain flour
a splash of milk
tiny dash of cold water

Preheat oven to 200C (for fan ovens). Grab a bun baking tray and add a teaspoon of vegetable oil into each one then put in the oven. Crack the egg into a bowl and add the flour. Whisk until it looks like a smooth paste. Add the milk and cold water and continue to whisk. Take out the bun baking tray and pour the mixture into each bun section. Cook for 20 minutes until soft and golden brown.
