Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the fat and liquid into a smooth gravy as its starch swells when heated.
- Fat
- Carries flavor from the roast and, combined with flour, forms the base for thickening.
- Hot water or stock
- Forms the liquid body of the gravy and carries the drippings' flavor.
- Mushrooms
- Adds savory, earthy flavor to the gravy.
The step that matters
Stir flour into the hot fat until well mixed. Cooking flour in fat coats the starch granules so they disperse evenly. Adding liquid to clumpy or unmixed flour causes lumps that are hard to remove.
