Mongolian Beef

"This is a traditional Mongolian beef recipe that I have worked on for over a year to perfect. My husband and I love Chinese food, and now we make it at home -- even better than the restaurant!"

Why it works: Oyster and chard work together. They rank in the top 30% of all ingredient pairs, and 3 recipes mention both. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓

Ingredients

Contains: wheat, peanut, soy, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Whisk the chicken stock, cornstarch, hoisin sauce, oyster sauce, dry sherry, sugar and soy sauce in a bowl until smooth, then set aside.

  2. Pat the sliced flank steak dry and toss it with the salt and black pepper.

  3. Heat the peanut oil in a large skillet or wok over high heat. Cook the beef in batches, in a single layer, for 1 to 2 minutes per side until browned and it reaches 145°F (63°C) in the thickest part. Let the beef rest 3 minutes, then remove it from the pan.

  4. Lower the heat to medium-high. Add the hot chili oil and crushed red pepper flakes and cook for 30 seconds, then add the chopped garlic and stir for 30 seconds.

  5. Add the sliced Swiss chard to the pan and stir-fry for 2 to 3 minutes until just wilted.

  6. Return the beef and any juices to the pan. Stir the sauce mixture again and pour it in. Cook 1 to 2 minutes, stirring, until the sauce thickens and coats the beef.

  7. Scatter the green onion slivers over the beef, toss once more and serve hot.

Fit is the average pairing score against chicken, sauce, oyster, sherry, sugar, pepper, peanut oil. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
