Why it works: Garlic and onion match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 29,058 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓
Tomato Sauce
Ingredients
Directions
Make the tomato base
Cook the tomato, water, garlic, pepper berry, and parsley for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomato
- Provides the main body and tomato flavour of the sauce.
- Butter
- Carries the onion's flavour and adds richness to the sauce base.
- Flour
- Thickens the sauce when cooked with the butter and onion.
- Onion
- Adds savoury aromatic depth after browning in butter.
The step that matters
Add flour to the onion and stir to create a white sauce. Flour must be stirred into the browned butter and onion so it cooks evenly; if it clumps or is not stirred enough, lumps form and the sauce thickens unevenly.
Flavor stand-ins for the berry
How well each one fits the dish's main ingredients (tomato, butter, clove, garlic, onion, pepper, flour):
- Avocadobetter flavor fit
- Limebetter flavor fit
- Cherrybetter flavor fit
- Berrythe original
Fit is the average pairing score against tomato, butter, clove, garlic, onion, pepper, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
