Zapallitos rellenos

Zapallitos rellenos: round summer squash baked with a filling of their own flesh, onion, pepper, cheese and breadcrumbs

Round green zapallitos, the size of a tennis ball, pile up at every verdulería in Buenos Aires from December to March, and stuffing them is how home cooks turn a cheap summer vegetable into a main course. The shells are blanched, hollowed and refilled with their own flesh fried with onion and red pepper, bound with egg and melting cheese, and topped with breadcrumbs that bake to a crunchy lid. Expect a soft, savoury, slightly creamy filling under a golden crust; serve two per person with a tomato and onion salad or white rice. Overcooking the shells in the first boil is the trap: they collapse in the oven and leak water, so they only get 4 minutes. Round courgettes, eight-ball squash or short fat courgettes all work. The cheeses are usually made with animal rennet; swap in vegetarian versions if needed. Chef's tip: squeeze the chopped flesh in a clean cloth before frying it; drier filling means a firmer, tastier stuffing.

Method

0/9 done
  1. Step 1: Simmer 8 round courgettes (zapallitos) whole in a large pot of salted water until a skewer pierces the skin but meets resistance in the middle.

    4 min
  2. Step 2: Drain, cool for a few minutes, then cut off a lid from each and scoop out the flesh with a teaspoon, leaving a 5 mm shell. Turn the shells upside down to drain.

  3. Step 3: Chop the scooped flesh and squeeze it hard in a clean tea towel to remove the water.

  4. Step 4: Heat 2 tbsp sunflower or olive oil in a frying pan over a medium heat and cook 1 onion and 1 red pepper until soft and sweet.

    8 min
  5. Step 5: Add 1 clove garlic and the squeezed flesh and cook, stirring, until the pan looks dry.

    5 min
  6. Step 6: Cool the mixture slightly, then stir in 1 egg, 5 ½ oz mozzarella or mild melting cheese, 1 ⅜ oz grated hard cheese, ⅞ oz dried breadcrumbs, ½ tsp salt and 1 pinch ground nutmeg. Heat the oven to 400°F (350°F fan).

  7. Step 7: Pack the filling into the shells, set them in an oiled baking dish and sprinkle with ⅞ oz dried breadcrumbs.

  8. Step 8: Bake until the tops are deep golden and the filling is bubbling at the edges.

    25 min
  9. Step 9: Scatter with parsley if using and serve hot or warm, two per person.

Caramelised clay-pot 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.

Spinach with mushrooms

A bright green, savoury puree of potato, mushrooms and fresh spinach cooked in home-made baby stock. Thick and smooth, it's a good way to get iron-rich greens into babies of 8–18 months. Serve warm; spare portions freeze well.

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.
