Why it works: Spinach and sesame match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 203 recipes mention both. Both carry 2-methoxy-4-vinylphenol, which smells clove, smoky. The science ↓

The recipe

Ingredients

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

Directions

Prepare the vegetables

  1. Soak the Chinese black mushrooms in 1 cup hot water for 20 minutes.

  2. When they have softened, cut off the hard stems and slice the caps finely.

  3. Drop the spinach into 10 cups of boiling water. Boil rapidly for 2 minutes. Run under cold water.

  4. Squeeze out as much moisture as possible.

  5. Peel the carrot, cut into 3 sections, then into fine julienne strips.

  6. Wipe off the fresh mushrooms and break off their stems. Cut the caps into very fine slices. Cut the non‑woody part of the stems into matchstick pieces.

  7. Cut away and discard the curly tender part of the cabbage leaves. Save only the V‑shaped core of the leaves. Cut this into julienne strips.

  8. Cut the scallions into 2‑½‑inch sections. Quarter the section with the bulb lengthwise.

  9. Combine the Chinese mushrooms, spinach, carrot, zucchini, mushrooms, cabbage, and scallions in a bowl. Mix well, separating all the spinach leaves.

Stir-fry and season

  1. Heat the vegetable oil and sesame oil in a wok or a 10‑inch sauté pan over a medium‑high flame. When hot, add the garlic. Stir and fry for 10 seconds.

  2. Add all the vegetables in the bowl. Stir and fry for 3 to 4 minutes or until the vegetables are tender‑crisp.

  3. Turn the heat to low.

  4. Add the drained noodles, soy sauce, and salt. Stir well, distributing the noodles evenly, and cook 2 to 3 minutes; taste for seasonings.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cellophane mung-bean noodles
Form the bulk of the dish and absorb the seasoning sauce.
Spinach
Adds leafy body and moisture that the squeezing step controls.
Chinese black mushrooms
Contribute a deep, savory umami flavor and chewy texture.
Garlic
Adds aroma when fried briefly in hot oil.
Soy sauce
Provides salty, savory flavor that seasons the noodles and vegetables.

The step that matters

Squeeze the spinach dry after blanching. Excess water left in the spinach dilutes the seasoning and steams the vegetables instead of letting them stir-fry, leaving the dish wet and bland.

Flavor stand-ins for the cabbage

How well each one fits the dish's main ingredients (mushroom, spinach, carrot, sesame, garlic, sauce, sugar):

  1. Capsicumbetter flavor fit
  2. Tomatobetter flavor fit
  3. Broccolibetter flavor fit
  4. Cabbagethe original

Fit is the average pairing score against mushroom, spinach, carrot, sesame, garlic, sauce, sugar. 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).
