Why it works: Tarragon and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,399 recipes. Both carry estragole, which smells anise, licorice. The science ↓
The Epicure's Hash
Ingredients
Directions
Make the sauce
In a stew pan, melt the butter and fry the sliced onions until brown.
Add the broth, Harvey sauce, tarragon vinegar, curry paste, sugar, salt, and pepper.
Bring the sauce to a boil, then reduce heat and simmer for 30 minutes, stirring often.
Mix the flour with a little cold water until smooth, then add to the sauce to thicken.
Finish and serve
Once the sauce has boiled thoroughly, add the sliced mutton and heat through without boiling.
Serve hot with pieces of toast around the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat that is warmed through in the finished sauce.
- Onions
- Browning in butter builds a sweet, savoury base for the sauce.
- Flour
- Thickens the sauce as it is heated, giving it body.
- Broth
- Forms the liquid base of the sauce, carrying the other flavors.
- Tarragon vinegar
- Adds acidity that brightens and balances the rich sauce.
The step that matters
Heat the mutton through without boiling. Boiling toughens meat proteins and makes them dry and stringy, so the mutton should only be warmed in the finished sauce.
Swap the onion
How well each one fits the dish's main ingredients (mutton, butter, sauce, tarragon, vinegar, sugar, pepper):
- Shallotfits better
- Mustardfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against mutton, butter, sauce, tarragon, vinegar, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
