Add the courgettes plus 1 tbsp oil and some freshly ground black pepper to the batter and mix thoroughly. Heat a little oil in a large frying pan (or two smaller ones at once) and, when it’s very hot, ladle in enough mixture to cover the base completely. Cook until the underneath is set, then slide it out onto a plate and invert it back into the pan to cook the other side. Slide out the cooked pancake and keep warm in a low oven while you make more. Using an average-size frying pan, you should end up with 4 thick pancakes.
