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

What each ingredient does

Sweetbreads: Provide the tender, meaty body of the filling.
Flour: Thickens the stock into a smooth, cohesive sauce.
Butter: Adds fat and richness to the sauce.
Mushrooms: Add earthy flavour and a soft, chewy texture.

The step that matters

Whisk in flour and salt until smooth. Flour clumps if added to hot liquid without being whisked in thoroughly. Whisking it into the melted butter and stock while stirring keeps the starch dispersed, so the sauce thickens evenly.
