The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Fat
- Carries flavor and forms the base of the roux with the flour.
- Flour
- Thickens the gravy as it cooks with the fat and stock.
- Stock
- Forms the liquid body of the gravy and carries its savory flavor.
The step that matters
Gradually pour in the stock while stirring constantly. Adding liquid slowly while stirring keeps the flour smooth and evenly dispersed. Pouring it in all at once can trap clumps of starch that stay lumpy and fail to thicken evenly.
