Asparagus crespelle

Method

1. Put the flour, milk and eggs in a food processor and whizz until smooth. Season. Heat an oiled 23cm frying pan over a medium heat. Add 2 tablespoons of batter, swirling to cover the pan base. Cook for 1-2 minutes, flip over and cook for a further minute. Slide onto a plate and repeat to make 12 crespelles. Layer the crespelles between sheets of baking paper to prevent sticking.
2. Meanwhile, preheat the oven to 240°C/fan220°C/gas 9. Put the asparagus in a roasting tin, toss with the oil and roast for 7 minutes or until tender. Set aside.
3. Reduce the oven temperature to 220°C/fan200°C/gas 7. Stir the Parmesan into the white sauce and season with some nutmeg. Spread a little onto a crespelle, top with some asparagus and Fontina. Roll up and put into a 2-litre ovenproof dish. Repeat with remaining ingredients.
4. Drizzle with the remaining sauce, sprinkle with the extra cheeses and some nutmeg. Bake for 12-15 minutes or until golden. Serve immediately.
