Why it works: Mushroom and butter 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 ↓
Mushroom Croutes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the mushrooms
Melt the butter in a pan.
Remove gills from mushrooms, wash, and chop them.
Cook the mushrooms in the melted butter.
Add breadcrumbs, salt, pepper, and cayenne to the mixture.
Assemble and bake
Place the mixture on croûtes (toasted bread).
Cook the roe in a dripping tin in the oven at 350°F (175°C).
Cut the cooked roe into pieces and place one on each croûte.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Form the main savoury filling and add earthy flavour and moisture as they cook in butter.
- Soft herring roe
- Adds a rich, savoury, slightly creamy topping that stands out against the mushrooms.
- Breadcrumbs
- Absorb the butter and mushroom juices, giving the filling body so it holds on the croûtes.
- Butter
- Carries the mushrooms' cooking and adds richness and fat for flavour.
The step that matters
Cook the roe in a dripping tin in the oven at 350°F (175°C).. Soft roe is delicate and can overcook quickly, turning dry and grainy. Gentle, moderate oven heat sets it through while keeping it tender and moist.
