Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften into a sweet, moist base for the stuffing once blanched and simmered.
- Butter
- Adds richness and fat that carries the sage flavour and keeps the stuffing moist.
- Bread crumbs
- Absorb the cooking juices and bind the stuffing into a cohesive mixture.
- Sage leaves
- Contribute the herbal aroma that defines the stuffing's flavour.
The step that matters
Simmer the onion mixture gently. Gentle simmering softens the onions and drives off excess liquid without scorching the butter. Stirring occasionally keeps the mixture from sticking and burning on the base of the stewpan, which would make the stuffing taste bitter.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (onion, sage, butter, pepper, bread):
- Lemonfits better
- Limefits better
- Avocadofits about as well
- Applethe original
Fit is the average pairing score against onion, sage, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
