Why it works: Tomato and basil are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,979 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
French Tomato Sauce
Ingredients
Directions
Make the sauce
Place quartered tomatoes in a saucepan with salt, basil, garlic, and a little water to prevent sticking.
Cook until thoroughly done.
Strain through a fine sieve to remove excess water.
Transfer the tomato pulp back to the saucepan.
Boil for 30 minutes.
Add black pepper to taste.
Bottle and store
Pour the sauce into wide-mouthed bottles.
Cork tightly and secure with string or wire.
Dip the neck of each bottle in melted resin for preservation.
Store in a cool place.
Once opened, use promptly.

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, acidity and flavour of the sauce as they cook down.
- Garlic
- Adds pungent aroma that mellows and deepens during the long simmer.
- Fresh basil
- Contributes a fresh, aromatic herbal flavour to the sauce.
The step that matters
Straining through a fine sieve. Removing excess water before the final boil controls the sauce's thickness. Leaving too much liquid makes the sauce thin and watery, and it may take longer to reduce and concentrate its flavour.
