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

What each ingredient does

Sweetbreads: Provide the tender, delicate meat that forms the body of the dish.
Butter: Enriches the sauce and carries flavor when melted with the flour.
Flour: Thickens the cream into a smooth sauce that holds the filling together.
Cream: Forms the rich, smooth sauce that is brought to a boil and thickened.
Mushrooms: Add earthy flavor and a soft texture to the creamed filling.

The step that matters

Stirring the sauce as it boils. Flour thickens cream only when it is stirred constantly while heating; otherwise it can clump and leave the sauce lumpy and uneven.

Swap the white pepper

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