Lomo saltado: Peruvian beef and chip stir-fry

Peru's much-loved mash-up of Chinese wok cooking and local flavour: sizzling beef, onions and tomatoes in a tangy soy sauce, tossed with chips and served with rice. Chips and rice on one plate is the whole point.

Ingredients

Method

  1. Cook the oven chips according to the packet until really crisp; you want them sturdy enough to toss with the sauce.
  2. Meanwhile, boil the rice in salted water, drain and keep warm with a lid on.
  3. Toss the beef with the cumin, pepper and a pinch of salt.
  4. Get a wok or large frying pan smoking hot with half the oil. Sear the beef in two batches so it browns rather than stews, about 2 minutes a batch, then tip onto a plate.
  5. Add the rest of the oil and the onion wedges and stir-fry for 2 minutes so they soften but keep some bite. Add the garlic and chilli for 30 seconds, then the tomatoes for 1 minute. Pour in the soy and vinegar, return the beef and its juices and let it bubble for a minute.
  6. Take off the heat, toss in the hot chips and most of the coriander, and serve straight away with the rice and the last of the coriander.
