Heat a splash of oil and a small knob of butter in a non-stick frying pan until sizzling. Pour in rounds of the batter, approximately 7-8cm wide. Do this in batches to ensure there’s plenty of space between each. The batter should sizzle a little as it hits the pan, but not aggressively – adjust the heat if needed. Cook until bubbles start to form on the surface, then flip and cook on the other side until golden, about 2 mins on each side. Eat straight away or keep warm in a low oven while you cook the rest. Serve with maple syrup.
