Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Gravy for Roast Turkey
Ingredients
Directions
Make the broth
Combine the turkey neck, heart, liver, and gizzard with 1½ cups of cold water and ½ teaspoon of coarse sea salt in a saucepan.
Boil gently until tender.
Remove the neck and leave the gizzard whole.
Finish the gravy
Finely chop the liver and heart or pass them through a sieve.
Mix in a small piece of butter and a little flour.
Return the mixture to the saucepan with the reserved water.
Add ¼ teaspoon of black pepper.
Boil gently, stirring constantly until smooth.
Optionally, remove fat from turkey drippings and stir it into the gravy.
Boil for a few minutes before serving.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the liquid into a smooth gravy as it cooks.
- Butter
- Adds richness and fat, which carries flavor and smooths the gravy's texture.
The step that matters
Stirring constantly until smooth. Flour mixed into hot liquid can clump if not stirred. Constant stirring keeps the starch dispersed so it thickens evenly into a smooth gravy.
