Why it works: Parsley and pepper 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 ↓

Ingredients
Directions
Put the tomatoes and all the other ingredients into a saucepan.
Stir continuously until the tomatoes are thoroughly melted and the sauce is thick.
Strain the sauce through a tammy (fine sieve) and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and bright acidity, and break down into the sauce's thickness as water evaporates.
- Butter
- Adds fat that carries flavour and gives the finished sauce a smooth, rounded mouthfeel.
- Large onions
- Contribute savoury aroma and some sweetness as their sugars develop during cooking.
The step that matters
Stir continuously until the sauce is thick. As water evaporates and the tomatoes break down, the sauce thickens. Sugars from the onions and tomatoes can scorch quickly on the hot base of the pan, so constant stirring keeps the sauce from catching and burning.
Swap the raisin
How well each one fits the dish's main ingredients (tomato, butter, onion, parsley, clove, wine, pepper):
- Lemonfits better
- Limefits better
- Avocadofits better
- Raisinthe original
Fit is the average pairing score against tomato, butter, onion, parsley, clove, wine, pepper. Candidates are from the same food group and used in at least 100 recipes.
