Why it works: Onion and sage are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 3,628 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sage and Onion Seasoning for Ducks and Geese
Ingredients
Directions
Prepare the onions
Peel the onions and score each one in thin slices without cutting all the way through.
Turn the onions and cut across the other way to create small pieces.
Cook
Place the onions in a saucepan with butter and salt.
Cover and cook on low heat for 30 minutes, shaking occasionally until softened but not burnt.
Mix in the sage and continue cooking until well combined.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Provide the bulk of the seasoning and, as they soften, sweetness and savoury flavour.
- Butter
- Adds fat that carries flavour and helps the onions soften gently without sticking.
- Sage
- Supplies the herbal, aromatic flavour that defines the seasoning.
The step that matters
Cooking the onions covered on low heat. Low, covered heat softens the onions and draws out their sugars slowly. Too much heat or too little attention can scorch the sugars, leaving a bitter, burnt taste instead of a sweet, mellow one.
Swap the sage
How well each one fits the dish's main ingredients (onion, butter):
- Garlicfits better
- Capersfits better
- Thymefits better
- Sagethe original
Fit is the average pairing score against onion, butter. Candidates are from the same food group and used in at least 100 recipes.
