Sugar and vanilla share little aroma chemistry, yet 35,031 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

Flavor stand-ins for the walnut

How well each one fits the dish's main ingredients (flour, butter, sugar, vanilla, almond, egg):

  1. Chestnutabout as good a flavor fit
  2. Pecansabout as good a flavor fit
  3. Hazelnutabout as good a flavor fit
  4. Walnutthe original

Fit is the average pairing score against flour, butter, sugar, vanilla, almond, egg. 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).
