Flamiche aux poireaux

Leek and cream tart

Flamiche picarde, the leek and cream tart of Picardy

Flamiche means 'cake' in old Flemish, and in Picardy, around Amiens and Abbeville, it is a tart of leeks melted slowly in butter and set in eggs and cream, baked in a crisp pastry case and sometimes covered with a pastry lid. The leeks from the market gardens (hortillonnages) of Amiens are famous, and flamiche is served warm as a starter or as a supper with green salad, especially from autumn to spring. The leeks must be cooked until soft and sweet, never browned. Chef's tip: squeeze the cooked leeks in a sieve before adding the custard; any water left in them stops the filling from setting and soaks the pastry.

Method

0/6 done
  1. Step 1: Rub 3 ⅞ oz cold unsalted butter into 8 oz plain flour and ½ tsp salt until it looks like breadcrumbs, then mix in 4 tbsp cold water to a firm dough. Wrap and chill for 30 minutes.

    35 min
  2. Step 2: Melt 1 ⅜ oz unsalted butter in a wide pan, add 1 ¾ lb leeks and a splash of water, cover and cook over a low heat for 20 minutes, stirring now and then, until very soft, sweet and collapsed but not coloured. Tip into a sieve to drain and cool.

    20 min
  3. Step 3: Heat the oven to 400°F (350°F fan) with a tray inside. Roll the pastry 3 mm thick and line a 24 cm tart tin. Prick the base, line with baking paper and baking beans and bake for 15 minutes; remove the paper and beans and bake 5 minutes more, until the base looks dry.

    20 min
  4. Step 4: Whisk 3 eggs, ¾ cup crème fraîche, 1 pinch ground nutmeg, ½ tsp salt and ½ tsp black pepper. Press the leeks firmly in the sieve to squeeze out their liquid, then stir them into the custard. Common mistake: skipping the squeeze; the tart turns watery and the base goes soggy.

  5. Step 5: Turn the oven down to 350°F (325°F fan). Pour the filling into the pastry case and bake for 30–35 minutes, until set with only a slight wobble in the centre and golden in patches.

    35 min
  6. Step 6: Rest for 10 minutes before slicing. Serve warm with a green salad.

Sandwich grecKebab baguette

In Paris, a "grec" is the late-night kebab sandwich named after the Greek-run shops that first sold it in the Latin Quarter. On rue de la Huchette and rue Saint-André-des-Arts near Saint-Michel, students queue after a night out for crusty bread or pitta stuffed with meat shaved from a turning spit, lettuce, tomato and onion, a garlicky white sauce, and, the Paris touch, a handful of fries pushed right inside. This home version marinates chicken thighs in spiced yoghurt, sears them hard and slices them thin, with oven fries. It contains milk, egg (in the mayonnaise) and wheat. Chef's tip: slice the meat thinly across the grain after resting; thick chunks don't feel like a grec.

Basque burnt cheesecake

This crustless cheesecake was created in the early 1990s at La Viña, a pintxos bar in the old town of San Sebastián (Donostia) in the Basque Country, and is now famous around the world. It's baked very hot so the top caramelises almost black and the sides rise and crack, while the middle stays soft and creamy, almost runny. There's no base and no water bath, and the rough, rustic look is the point: it's lined with crumpled baking paper. La Viña uses a spoonful of wheat flour; cornflour does the same job and keeps it gluten free. Chef's tip: take it out of the oven while the centre still wobbles like a soft set custard; it firms up as it cools, and if it looks set in the oven, the middle will be dry instead of creamy.

BourrideFish stew with garlic sauce

Bourride is the fish stew of Sète and the Provençal coast, a quieter, creamier cousin of bouillabaisse eaten for Friday lunch and summer dinners by the sea. Firm white fish poaches in a broth of fennel, leek, orange peel and thyme, then the broth is thickened with a rich garlic aïoli until it turns silky and pale gold. It is high in protein and suitable as part of a balanced diet; skip the traditional bread or keep it to one thin slice, and serve with steamed greens. About 400 kcal and 8 g carbohydrate per portion. The usual mistake is letting the broth boil after the aïoli goes in, which splits it like scrambled egg. Chef's tip: use pasteurised egg yolks, and stir the broth over a low heat until it coats a spoon and reaches about 72 °C.
