The recipe
Ingredients
Contains: wheat, soy, sesame (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: sesame
Directions
Prepare
Soak dried tofu slices in hot water for 15 minutes.
When softened, cut into 1" squares, drain, and pat dry.
Cook the wheat noodles in boiling water until al dente, a little firm. Drain, rinse under cold water, and drain again.
Fry the tofu
Heat oil in wok over high heat, and deep‑fry the tofu cubes until golden brown. Remove from pan and drain.
Next deep‑fry the squares of dried tofu until golden brown and slightly blistered; remove and drain.
Stir-fry and serve
Heat sesame oil in another wok on full heat; sauté the minced ginger for 1 minute.
Add the asafoetida and choy sum and stir‑fry until soft.
Add the soy sauce, sambal oelek, lemon juice, tofu, and noodles. Stir‑fry for another 2 minutes or until the noodles are hot.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm tofu
- Provides protein-rich body and, once fried, a golden crust with a soft interior.
- Dried tofu
- Frying gives it a golden, slightly blistered crust and a chewy, firm texture.
- Wheat noodles
- Form the bulk of the dish, with a firm, al dente bite that holds up to stir-frying.
- Soy sauce
- Adds salty, savoury depth that seasons the noodles and tofu.
- Lemon juice
- Adds acidity that brightens the sauce and balances the salty and spicy flavours.
- Fresh ginger
- Adds a sharp, aromatic warmth that is released when sautéed in oil.
The step that matters
Rinse and drain the noodles well before stir-frying. Cooking to a slightly firm bite and rinsing away surface starch keeps noodles from clumping and turning gummy when they are tossed in the hot wok.
Flavor stand-ins for the asafoetida

Fit is the average pairing score against tofu, wheat, ginger, sauce, sambal, lemon, mung bean. 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).
