A Nice Way to Serve Cold Beef

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast beef
- Is the main meat, served sliced and sitting under the gravy.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Browned flour
- Thickens the liquid and adds a toasted, nutty flavour to the gravy.
- Catsup or wine
- Adds acidity and savoury depth to the sauce.
- Lemon
- Adds bright acidity that cuts through the richness of the beef and butter.
The step that matters
Simmer the mixture gently for 30 minutes. Gentle heat in a covered pan lets the flour thicken the liquid smoothly without scorching or boiling away. A hard boil can make the sauce lumpy or reduce it too much.
Swap the leek
The recipe marks leek as optional. How well each one fits the dish's main ingredients (beef, wine, lemon, butter, flour, parsley, potato):
- Shallotfits better
- Chivefits better
- Carrotfits about as well
- Leekthe original
Fit is the average pairing score against beef, wine, lemon, butter, flour, parsley, potato. Candidates are from the same food group and used in at least 100 recipes.
