Preheat the oven and oil the tin
Take the eggs and the milk for the batter out of the fridge in advance; the ingredients should be at room temperature. Set the oven to 175 °C (conventional, top and bottom heat). Using a brush, oil the base and sides of a round fixed-base tin about 26 cm in diameter, or a glass baking dish, with 1 dessertspoon (10 ml) of vegetable oil; a springform tin with a removable base will let the milk syrup leak out.
