Gratin de blettes

Swiss chard gratin

Gratin de blettes: Lyon and Provence Swiss chard stalks and leaves baked in béchamel under breadcrumbs

Gratin de blettes is a thrifty winter favourite in Lyon and across Provence, where Swiss chard is a staple of every market garden and both the white ribs and the green leaves are used. The stalks are boiled until tender, the leaves wilted, and everything is folded into a nutmeg béchamel and baked under crisp breadcrumbs. It is served as a side with roasts or on its own for supper. The common mistake is not cooking the stalks long enough, which leaves them stringy. Chef's tip: peel the strings off the backs of the wide stalks like celery; the gratin will be silky.

Method

  1. Step 1: Heat the oven to 400°F (350°F fan). Cut the green leaves from the 2 ¼ lb Swiss chard. Pull the strings from the stalks and cut them in 3 cm pieces; roughly chop the leaves.

    5 min
  2. Step 2: Boil the stalks in water with the 1 tbsp salt for 8–10 minutes until tender, adding the leaves for the last 2 minutes. Drain well and squeeze the leaves dry.

    10 min
  3. Step 3: Melt the 1 ⅜ oz butter, stir in the 1 ⅜ oz plain flour and cook for 1 minute, then whisk in the 2 cups whole milk a little at a time. Simmer for 5 minutes, whisking, until thick and smooth. Season with 1 pinch ground nutmeg, ½ tsp salt and ½ tsp black pepper.

    8 min
  4. Step 4: Fold the chard into the sauce and spread in a buttered baking dish. Scatter over the 1 ¾ oz grated Gruyère or vegetarian hard cheese, 3 tbsp dried breadcrumbs and ½ oz butter.

    2 min
  5. Step 5: Bake for 20–25 minutes, until bubbling at the edges and golden and crisp on top.

Black bean tacos with lime slaw

Proof that a meat-free taco night can be the best one. The beans are mashed with chipotle and cumin so they hold together in the tortilla, and a quick lime slaw adds crunch.

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.

Caramelised clay-pot tofu and mushroomsBraised tofu and mushrooms

Kho is the slow braise of the Mekong Delta: food simmered in a little clay pot (nồi đất) with dark caramel and seasoning until the sauce is sticky and the flavours go deep. This vegetarian cousin of cá kho tộ (braised fish) uses golden tofu and meaty mushrooms in place of fish, cooked in coconut water, as cooks do in the south, and finished with plenty of black pepper. Serve it bubbling in its pot with steamed rice and a sour soup or plain boiled vegetables. Chef's tip: take the caramel (nước màu) to a deep mahogany, darker than you think, just before it smokes; pale caramel only tastes sweet, while dark caramel gives the bittersweet, smoky flavour of a real kho.
