Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Provide the main body and flavor of the sauce as they break down into pulp.
- Fresh butter
- Adds richness and a silky mouthfeel that gives the sauce its body.
The step that matters
Rub the mixture through a fine sieve. Pressing the cooked pulp through a fine sieve removes seeds and skins, giving the sauce a smooth texture. Skipping or rushing this leaves the sauce grainy.
Swap the white pepper
How well each one fits the dish's main ingredients (tomato, butter, sugar, pepper):
- Cinnamonfits better
- Thymefits better
- Basilfits better
- White pepperthe original
Fit is the average pairing score against tomato, butter, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
