  3. Add the salt and cook for 10 minutes.

Make the gravy

  1. Melt the butter in a separate pot, then add the flour and water to make a thin paste.

  2. Combine the soup stock, salt, and white pepper with the paste and cook until the gravy thickens.

  3. Cover the spaghetti with the hot gravy.

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

What each ingredient does

Spaghetti
Forms the bulk of the filling and holds its shape through cooking and processing.
Butter
Adds fat and richness to the gravy and carries flavor.
All-purpose flour
Thickens the gravy as its starch swells with heat.
Chicken or beef soup stock
Provides the liquid base and savory flavor of the gravy.

The step that matters

Thickening the gravy. Flour must be cooked in the fat and liquid until the gravy thickens so the starch swells and the sauce coats the spaghetti rather than separating or tasting raw and pasty.

Swap the white pepper

How well each one fits the dish's main ingredients (chicken, butter, flour):

  1. Jalapenofits better
  2. Capersfits better
  3. Garlicfits better
  4. White pepperthe original

Fit is the average pairing score against chicken, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
