• Sharp chef’s knife
• Cutting board
• Instant-read thermometer
• 1 medium mixing bowl (1–2 cup capacity) for sauce
• Tongs or metal spatula
• Plate for resting cooked beef

Ingredients (4 servings)

• Beef sirloin or flank steak — 1.5 lb (24 oz), trimmed and cut into 1/2-inch strips
• Red onion — 1 large (about 10 oz), cut into 1/2-inch wedges
• Tomato — 2 medium, cored and cut into 8 wedges each
• Scallions — 4 whole; whites and greens separated, slice whites 1/4-inch thick and greens into 1-inch lengths
• Garlic — 3 cloves, minced (about 1 tbsp)
• Soy sauce — 3 tbsp
• Red wine vinegar — 2 tbsp
• Ají amarillo paste — 1 tbsp (mild) — Practical substitution: if unavailable, use 1 tbsp mild yellow pepper purée or 1 tsp sweet paprika blended with 1/4 tsp mild chili paste (start smaller for children).
• Vegetable oil (neutral, high-heat) — 3 tbsp
• Kosher salt — 1 tsp
• Black pepper, ground — 1/2 tsp

Practical substitutions

• Beef: use skirt steak or top round if sirloin/flank unavailable; slice thin across the grain.
• Ají amarillo paste: substitution listed above.

Cooking / Baking

• High, direct stovetop heat. Target internal temperature for beef: 145°F (63°C) for medium doneness (adjust to preference but do not undercook if feeding children). Total active cook time (not counting mise en place): 12 minutes.

Instructions

1. Measure and arrange all sauce ingredients: in the mixing bowl whisk together 3 tbsp soy sauce, 2 tbsp red wine vinegar and 1 tbsp ají amarillo paste; place next to the stove.
2. Season sliced beef evenly with 3/4 tsp kosher salt and 1/4 tsp black pepper; set aside on a plate.
3. Heat the empty 12-inch wok or heavy skillet over high heat until it is very hot (1–2 minutes). Add 1 tbsp vegetable oil and swirl to coat.
4. Add half the beef in a single layer (do not crowd). Sear, tossing or turning pieces, until browned and registers 130–145°F for medium (about 2–3 minutes). Remove seared beef to plate. Repeat with remaining 1 tbsp oil and remaining beef, searing 2–3 minutes; remove beef to plate.
5. With wok still on high, add remaining 1 tbsp oil and immediately add the red onion wedges. Stir-fry 2 minutes until edges are blistered but not fully soft.
6. Add minced garlic and scallion whites; stir 30 seconds until fragrant.
7. Add tomato wedges and the soy/aji/vinegar mixture; stir 45 seconds to combine and bring sauce to a quick simmer.
8. Return all cooked beef to the wok; toss vigorously 1–2 minutes until beef is heated through, sauce coats ingredients and internal temperature is at least 145°F. Taste and add remaining 1/4 tsp kosher salt only if needed.
9. Stir in scallion greens for 10–15 seconds. Transfer immediately to a warmed serving dish and serve at once.

5. NOTES & ASSUMPTIONS

• Optional table-side items: lime wedges or extra ají amarillo paste for adults who want more brightness or heat.
• Global substitution note: if ají amarillo paste is unavailable, use the Practical substitutions listed under Lomo Saltado.
• Child-safety notes: keep children away from the stovetop during high-heat searing; use tongs and keep pan handles turned inward.
• Timeline risk(s): the tightest execution window is 16:48–17:00 when you sear beef in batches and finish the stir-fry while rice is resting; risk of overcooking or undercooking beef if pan temperature or timing slips.
• Practical mitigation mindset: have all ingredients trimmed/sliced and sauces measured before heating the wok; preheat the pan until very hot so searing is fast; work confidently and keep the sequence—sear beef in two quick batches, then finish vegetables and combine.
• The latest safe start time in plain language: You can start as late as 16:33 for a 17:00 serve.
