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

What each ingredient does

Butter: Enriches the sauce and carries flavour while forming the base roux with flour.
Flour: Thickens the milk into a smooth sauce when cooked with the melted butter.
Milk: Forms the liquid of the sauce, which thickens as the starch gelatinises.
Sweetbreads: Provide the tender, rich meat that the creamy sauce coats.
Green peas: Add sweetness and a bright colour and texture to the creamy sauce.

The step that matters

Gradually add the milk, stirring continuously until thick. Adding milk slowly while stirring keeps the flour evenly dispersed, preventing lumps. The sauce thickens as starch granules swell and gelatinise with heat, so it must be stirred until it reaches the right thickness.
