Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Stewed Sweet-bread with Champignon
Ingredients
Directions
Prepare
Parboil the sweetbreads, then remove all skin and fat.
Cut the sweetbreads into small pieces and place them in a saucepan with the chopped champignons and their liquid.
Cook
Add the butter and a pinch of cayenne pepper.
Cook the champignons for 30 minutes before adding the sweetbreads.
Just before serving, stir in the Madeira or sherry, thicken with flour, and brown with burnt brown sugar.

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 stew.
- Champignons
- Add savoury, earthy flavour and moisture to the stew.
- Butter
- Adds richness and fat that carries flavour through the stew.
- Madeira or sherry
- Adds acidity and sweet, wine-based aroma near the end of cooking.
- Flour
- Thickens the cooking liquid into a smooth sauce.
The step that matters
Adding the sweetbreads after the mushrooms. Cooking the champignons for 30 minutes first lets their liquid release and reduce, building flavour before the delicate sweetbreads go in. Adding them too early risks overcooking and toughening the sweetbread.
