Step 2: Preheat an oven to 220 degrees with a muffin tray or oven proof dish with a touch of oil in (its important that the oven and oil are really hot before adding the batter) give the oil 10 minutes in the oven before adding the batter.
Step 4: If using a 6 holed muffin tray, fill each hole half-way with the batter and leave in oven (do not open) for about 15 minutes.
