Why it works: Mustard and cucumber match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 2,281 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fried Fish with Sauce
Ingredients
Directions
Prepare the fish

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify with the oil and mustard to give the sauce a thick, creamy body.
- Cornmeal
- Forms a crisp, golden coating on the fish as it fries.
- Vinegar
- Adds acidity that brightens the rich, creamy sauce.
- Pickled cucumbers
- Add tart crunch and acidity to the sauce.
- Mustard
- Adds sharpness and helps stabilise the emulsified sauce.
The step that matters
Cream the egg yolks with the oil. Yolks must be worked slowly with the oil so it emulsifies into a smooth, thick sauce. Adding the oil too fast, or adding the vinegar before the emulsion forms, can cause it to split and look greasy.
Swap the cucumber
