Why it works: Turkey and walnut share more aroma than cooks usually use. They rank in the top 17% of all ingredient pairs, and 14 recipes mention both. Both carry 2-hexenal, which smells green, leafy. The science ↓

Butter and flour share little aroma chemistry, yet 122,858 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turkey, fowl, or rabbit
- Provides the main meat that is stewed until tender in the sauce.
- Butter and flour
- Form a roux that thickens the sauce and gives it body.
- Veal stock
- Supplies the liquid base and savory depth of the sauce.
- Walnut ketchup
- Adds a dark, savory, slightly tangy flavour to the sauce.
The step that matters
Straining the mixture into the first stewpan. Straining removes the onion and any lumps from the roux and sauce, leaving a smooth liquid that thickens evenly around the meat without grittiness.

Fit is the average pairing score against turkey, butter, flour, veal, lemon, walnut, ketchup. 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).
