Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Smoked bacon
Lardoons add fat and smoky flavor that penetrate the meat as it cooks.
Butter
Fat that is cooked with flour to form a roux, giving the sauce body and richness.
Flour
Thickens the sauce when cooked in butter and combined with the liquid.
Sour cream
Adds creaminess and a tangy acidity that rounds out the sauce.
Vinegar
Adds acidity to the cooking liquid, sharpening the flavor of the gravy.

The step that matters

Diluting the butter-flour mixture. Adding the liquid to the roux gradually and stirring well prevents lumps, because flour starch clumps when it hits hot liquid without being dispersed first.

Swap the lemon
