Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watercress
- Forms the leafy base of the salad, providing crisp texture and fresh, peppery flavor.
- Soy sauce
- Adds salty, savory depth to the dressing.
- Sugar
- Balances the sharpness of the vinegar and soy sauce with sweetness.
- White vinegar
- Adds acidity that brightens the dressing and cuts through the oil.
- Sesame seeds
- Add toasty aroma and a nutty crunch when toasted and sprinkled on top.
- Onion
- Sautéed until golden, it adds mellow sweetness and savory flavor to the dressing.
The step that matters
Toasting the sesame seeds. Sesame seeds can go from fragrant to burnt within moments in a dry pan. Constant stirring at medium-low heat lets them toast evenly, developing nutty flavor without bitterness.
