Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Trim and parboil the sweetbreads, then chop them finely with a silver knife.
Make the cream base
Boil the cream in a saucepan.
In a separate bowl, combine the butter and flour, then stir into the boiling cream until thick.
Remove from heat, add the sweetbreads, seasoning, and optional mushrooms; mix well.
Chill and set
Let the mixture cool in a cold place for at least 4 hours to set.
Fry and serve
Form the mixture into croquettes, dip in breadcrumbs, and fry in boiling fat.
Serve with a cream sauce.

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 filling.
- Cream
- Adds moisture and richness, and forms the base that thickens into the filling.
- Flour
- Thickens the boiling cream so the mixture becomes firm enough to set.
- Butter
- Adds fat and richness, and combines with flour to form a thickening base.
The step that matters
Chill until fully set. Cooling the thickened mixture for at least four hours lets it firm up so it holds its shape. Forming or frying it too soon can leave croquettes that slump or break apart in the hot fat.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, cream, onion, flour, parsley, mushroom):
