Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the fat base of the sauce and carries flavor into the liquid.
- All-purpose flour
- Thickens the sauce as it cooks with the butter and broth.
- Beef broth
- Provides the liquid body and savory flavor of the sauce.
- Pickled cucumbers or walnuts
- Add texture and a tangy, briny bite to the sauce.
- Vinegar
- Adds acidity that brightens the rich, buttery sauce.
The step that matters
Let the sauce simmer until it thickens. Flour thickens only as it heats and its starch swells, so the sauce must simmer long enough to reach the desired consistency. Stopping early leaves it thin and floury-tasting.
Swap the parsley
