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

What each ingredient does

Eggs
Beaten eggs set gently with the heat, thickening the sauce and coating the pasta creamily.
Butter
Adds fat and richness, helping the sauce coat the strands smoothly.
Parmesan cheese
Adds salty, savory flavor and helps thicken the sauce as it melts.
Bacon
Contributes smoky, savory flavor and rendered fat to the dish.
Milk
Adds moisture and mildness, loosening the egg mixture into a silky sauce.

The step that matters

Heat thoroughly, stirring occasionally. Eggs thicken as they heat but can scramble if overheated or left still. Gentle, frequent stirring keeps the sauce smooth and creamy rather than grainy.

Swap the parsley

How well each one fits the dish's main ingredients (egg, butter, milk, parmesan cheese, pepper):

  1. Parsleythe original
  2. Nutmegfits about as well
  3. Cinnamonfits less well
  4. Thymefits less well

Fit is the average pairing score against egg, butter, milk, parmesan cheese, pepper. Candidates are from the same food group and used in at least 100 recipes.
