Why it works: Berry and parsley share more aroma than cooks usually use. They rank in the top 10% of all ingredient pairs, and 16 recipes mention both. Both carry myristicin, which smells spice, warm. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned tomatoes
- Provide the main body and tomato flavour of the sauce.
- Butter
- Carries the browned flavour and forms the fat base for the roux.
- Flour
- Thickens the sauce by combining with the butter and absorbing the stock.
The step that matters
Adding the stock to the roux. Flour and butter form a roux that must be combined before liquid goes in. Adding stock gradually while stirring keeps the mixture smooth, because starch clumps if it meets hot liquid all at once. Cooking until thick lets the starch swell fully.
Flavor stand-ins for the berry

- Berrythe original
Fit is the average pairing score against tomato, clove, allspice, pepper, parsley, onion, butter. 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.
