Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable marrows
- Main vegetable; its moisture turns to steam inside the batter while it fries.
- All-purpose flour
- Forms the batter that coats the slices and sets into a crisp shell when fried.
- Egg yolk
- Adds richness and helps the batter bind to the vegetable.
- Egg whites
- Whisked in for air, making the batter light and frothy for a crisp, airy coating.
- Oil
- Adds fat to the batter, giving a tender texture and browning.
The step that matters
Frying in hot fat until golden brown. The fat must be hot enough to set the batter quickly. If it is too cool, the coating soaks up oil, turns greasy and fails to crisp.
Swap the parsley
How well each one fits the dish's main ingredients (pepper, flour, egg):
- Turmericfits about as well
- Parsleythe original
- Nutmegfits about as well
- Jalapenofits about as well
Fit is the average pairing score against pepper, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
