Place two identical large glasses on your work surface. Break the egg into one glass then place enough plain flour into the second glass until it's level with the egg in the first glass. Put the flour into the mixing bowl.
Now re-use the second glass and fill with milk up to the level of the egg. Pour both mixtures into the mixing bowl. Add 1 teaspoon oil to the mixing bowl. Mix together until the mixture is smooth. Leave it to stand.
Using small metallic non-stick mini cake tray, drizzle oil in each section. Use your finger to ensure the whole mini dish has been oiled.
Carefully place the baking tray into the oven and leave until the oil is hot, no more than 5 minutes.
Remove the baking tray and add about 1 tablespoon of the mixture to each section, using up all the mixture. Place it back in to the middle of the oven.
Bake until risen and golden brown, about 10 minutes Serve hot.
Sometimes I add a pinch of cumin, dried chopped chillies, curry powder, mixed dried herbs, thyme etc. to the mixture to alter the flavour.
