Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef bones
- Browned bones give deep, savory flavor and body to the sauce base.
- Veal bones
- Release gelatin during long simmering, adding body and a silky mouthfeel.
- Flour
- Thickens the sauce as it is stirred into the hot liquid.
- Good stock
- Forms the main liquid that extracts flavor and dissolves gelatin from the bones.
- Onions
- Sweetness and aromatic depth as they soften and brown with the bones.
- Carrots
- Add natural sweetness and aromatic background to the simmering liquid.
The step that matters
Stir in the flour before moistening with stock. Flour must be cooked into the fat and browned bits so it thickens smoothly. Adding it to hot liquid unevenly can form lumps, and adding too much makes the sauce pasty.
Swap the onion
