Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Hashed Turkey
Ingredients
Directions
Prepare the turkey
Cut the leftover turkey into small pieces.
Remove the upper warty part of the neck and head, but reserve the brains if desired.
Make the hash
Melt butter in a pan and sauté chopped onion until soft.
Add turkey pieces and cook until heated through.
Sprinkle with coarse sea salt and pepper to taste.
Stir in flour and add water to create a sauce.
Simmer until the mixture thickens, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover turkey
- Supplies the cooked meat that forms the bulk of the hash.
- Butter
- Adds fat and rich flavor to the pan and softens the onion.
- Onion
- Adds aroma and gentle sweetness as it softens in the butter.
- Flour
- Its starch swells with heat and thickens the liquid into a sauce.
The step that matters
Simmer until the mixture thickens. Flour starch only swells and thickens fully when heated long enough while simmering. Stopping early leaves the sauce thin and can leave a raw, floury taste.
Swap the onion
How well each one fits the dish's main ingredients (turkey, pepper, butter, flour):
- Capsicumfits better
- Shallotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against turkey, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
