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 gives it a rich, smooth flavour as it melts.
Flour: Thickens the milk into a smooth sauce when cooked with the melted butter.
Milk: Forms the liquid base of the sauce, which thickens as it cooks.
Sweetbreads: Provide the main meaty texture and substance in the dish.
Green peas: Add sweetness, colour and a tender bite to the dish.

The step that matters

Cooking the milk into the flour. Add the milk gradually and keep stirring so the starch in the flour hydrates evenly. Lumps form if the liquid goes in too fast, and the sauce only thickens properly once it is cooked long enough.
