Why it works: Thyme and celery match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 3,193 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Tomato Sauce
Ingredients
Directions
Prepare the tomatoes
Remove the stalks from the tomatoes and squeeze them to remove the seeds.
Cook the sauce
In a saucepan, combine the tomatoes, onion, thyme, bay leaf, celery, ham or bacon, butter, sugar, salt, and pepper.
Cook gently over low heat until everything is tender.
Stir in the flour and moisten with the broth, then boil for 5 minutes.
Add a little cayenne pepper and taste for seasoning.
Strain and thicken
Pass the sauce through a sieve or fine strainer.
Return the sauce to the saucepan and cook until it thickens enough to coat the back of a spoon.

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 fresh tomato flavour of the sauce.
- Butter
- Adds richness and fat, rounding out the acidity of the tomatoes.
- Flour
- Thickens the sauce as it is moistened and boiled with the broth.
- Broth
- Adds liquid and savoury depth, moistening the flour for thickening.
- Sugar
- Balances the acidity of the tomatoes for a rounder sweetness.
- Ham or bacon
- Contributes salty, savoury flavour to the sauce base.
The step that matters
Thickening with flour and broth. Flour must be stirred in and moistened fully before boiling, or it forms lumps. Boiling activates its starch so the sauce thickens. Cook until it coats the back of a spoon, since thickness is judged by that sign rather than time.
Swap the onion
How well each one fits the dish's main ingredients (tomato, thyme, celery, ham, butter, sugar, pepper):

- Onionthe original
Fit is the average pairing score against tomato, thyme, celery, ham, butter, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
