Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Mutton to Imitate Venison
Ingredients
Directions
Prepare the gravy
Cut the mutton into thin slices with some fat attached.
Stick a few cloves into the onion and place it in a stewpan with bay leaves, mace, sweet herbs, allspice, and clear gravy.
Boil gently for an hour.
Make the sauce
In another stewpan, melt butter and stir in flour until browned.
Strain in a small amount of the prepared gravy and mix smoothly.
Add the rest of the gravy and stir until boiling and thickened.
Add the mutton, port wine, mushroom ketchup, Worcestershire sauce, red‑currant jelly, and salt to the sauce.
Keep the stewpan on low heat without boiling the gravy again.
Serve
Boil and drain the spinach, chop it, and mix with butter.
Form a wall of spinach on a hot dish, pile the meat in the center, pour the sauce around, and serve.

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 becomes tender during long gentle simmering.
- Butter
- Melted with flour to form a roux that thickens the sauce and adds richness.
- Flour
- Browned in butter to form a roux that thickens the gravy into a smooth sauce.
- Red-currant jelly
- Adds sweetness and a fruity acidity that balances the savory, rich sauce.
- Mushroom ketchup
- Adds concentrated savory, umami depth to the sauce.
- Port wine
- Adds sweetness, body, and fruity aroma to the sauce.
The step that matters
Keep the sauce below a boil after adding the meat and wine. Once the sauce is thickened, boiling again can make the flour-thickened sauce break or turn thin and grainy, and can toughen the meat proteins. Gentle low heat keeps the sauce smooth and the meat tender.
Swap the mace
How well each one fits the dish's main ingredients (mutton, onion, allspice, butter, flour, port wine, mushroom):
- Thymefits better
- Clovefits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against mutton, onion, allspice, butter, flour, port wine, mushroom. Candidates are from the same food group and used in at least 100 recipes.
