Bistek Tagalog (Beef Steak with Onions)

Method

1. In a bowl, marinate the thin beef slices with soy sauce, calamansi or lemon juice, and pepper for at least 1 hour; 2–4 hours gives deeper flavour.
2. Heat a little oil in a pan and cook the onion rings until soft and lightly browned. Set aside.
3. In the same pan, add more oil if needed and quickly sear the beef slices in batches over high heat so they brown but do not overcook.
4. Return all the beef to the pan and add the marinade and water.
5. Simmer a few minutes until the beef is just cooked and the sauce has slightly reduced.
6. Add the onion rings back to the pan and toss gently in the sauce.
7. Taste and adjust with a little salt if needed, then serve hot with rice.
