How to cook deliciously - Pasta alla norma

1 . Stage

Toss the aubergines with the salt, then tip into a colander set over a bowl for 30 mins, to extract any moisture.

2 . Stage

Heat 2 tbsp of the oil in a casserole dish or saucepan. Tip in the onion and a pinch of salt, and cook over a low heat for 10 mins. Add the garlic and chilli, and cook for 1 min. Tip in the tomatoes and sugar, and bring to the simmer. Cook, uncovered, for 20 mins, stirring occasionally. Heat the oven to 220C/200C fan/gas 7.

3 . Stage

Pat the aubergine dry with kitchen paper, then toss with the remaining oil. Spread out on a baking sheet and roast for 25-30 mins until softened and golden around the edges. Meanwhile, cook the pasta following pack instructions, reserving 100ml of the cooking water.

4 . Stage

Stir the aubergine into the sauce with the basil and capers. Season to taste, then toss the spaghetti in the pan with the sauce and a splash of the pasta water. Divide between four bowls and top with the ricotta and extra basil, if using.
