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 ↓
Turkct, Hashed
Ingredients
Directions
Prepare the stock
Divide the turkey into small neat pieces and set aside.
In a stewpan, combine the bones and trimmings with a small onion, a blade of mace, a few peppercorns, and a little salt. Simmer gently for about 2 hours, then strain the stock.
Make the sauce
Melt the butter in a saucepan, stir in the flour, and add the stock. Stir until boiling, then let the sauce boil gently for about 10 minutes to cook the flour.
Season the sauce to taste, add the turkey pieces, and reduce heat to just below simmering for about 30 minutes.
Before serving, add a few drops of caramel to improve the sauce's color.
Serve
Garnish with toasted bread slices or a border of mashed potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Remains of cold roast turkey
- Forms the main body of the hash, supplying the meat that is gently heated in the sauce.
- Butter
- Adds richness and carries flavor, and with the flour forms the base of the sauce.
- Flour
- Thickens the stock into a sauce when cooked with the butter.
- Turkey stock
- Provides the liquid and savory flavor that makes the sauce.
The step that matters
Cooking the flour in the sauce. Boiling the flour and stock together for the full time cooks out the raw starchy taste and lets the starch thicken properly. Stopping early leaves the sauce pasty and floury.
Swap the mace
How well each one fits the dish's main ingredients (turkey, butter, flour, pepper, onion):
- Thymefits better
- Sagefits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against turkey, butter, flour, pepper, onion. Candidates are from the same food group and used in at least 100 recipes.
