Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that cooks the onion and carrot gently and carries flavor into the sauce.
- Flour
- Starch that thickens the stock or milk into a smooth, lightly bodied brown sauce.
- Lamb stock or milk
- Liquid that hydrates the flour and forms the body of the sauce.
- Canned roast beef
- Cooked meat that is heated through in the sauce, providing the main protein.
- Caramel
- Adds deeper color and a mild, slightly bittersweet flavor to the sauce.
The step that matters
Adding the cold stock or milk. Flour must be stirred smooth into the fat before cold liquid is added slowly. Adding liquid too fast or to hot fat can form lumps, because starch granules clump before they can disperse evenly.
