Torta Margherita
Potato starch sponge cake
A plain, cloud-light potato-starch sponge from Pavia, dusted with icing sugar
Torta Margherita has been baked around Pavia in Lombardy for centuries and is still the plain, yellow cake Italian grandmothers make for a child's birthday merenda or a Sunday breakfast. Potato starch gives it a fine, melting crumb, and a thick snowfall of icing sugar is all it needs, though children like it split and spread with jam. It contains egg, milk and gluten. Chef's tip: cream the butter and sugar for a full five minutes until almost white; that air is what makes the cake rise.

Method
0/6 doneStep 1: Heat the oven to 350°F (fan 300°F). Grease a 22 cm round tin and line the base with baking paper.
Step 2: Beat 4 ½ oz unsalted butter, 4 oz caster sugar and 1 tsp lemon zest with an electric mixer for 5 minutes, until pale and fluffy. Beat in the egg yolks from 4 eggs one at a time.
5 minStep 3: Sift 3 ½ oz potato starch, 1 ¾ oz plain flour and 1 ½ tsp baking powder together over the bowl and fold in until smooth.
Step 4: Whisk the egg whites to soft peaks, add the remaining 1 oz caster sugar and whisk until glossy. Fold them into the batter in three lots, gently, until no white streaks remain.
Step 5: Spread into the tin and bake for 35–40 minutes, until golden, the top springs back when pressed and a skewer comes out clean. Opening the oven before 30 minutes is the classic mistake: the delicate sponge collapses in the middle.
40 minStep 6: Cool in the tin for 10 minutes, then turn out onto a rack. When cold, dust thickly with 2 tbsp icing sugar through a sieve. Keep wrapped at room temperature for up to 3 days.

Boiled pasta
The basic method for any dried pasta, from penne to spaghetti. A large pan of salted boiling water keeps the pasta from sticking, and you cook it only until just done, with a little bite left. Use it in salads, bakes or with any sauce.
Minestrone soup
A hearty Italian vegetable soup with cannellini beans, cabbage and a little spaghetti, finished with a bright basil and tomato pesto stirred in at the end. Don't let it boil hard once the vegetables are in: over-boiled soups lose their colour and body. Serve hot with crisp garlic toast.
Cauliflower soup with farfalle
A smooth, creamy cauliflower soup flavoured with nutmeg and Parmesan, with little bow-tie pasta stirred through. It's served with crisp, curled melba toast sprinkled with Parmesan and paprika, so it makes a light meal on its own.
