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 Tartlets
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Peel and wash the mushrooms, then cut them into pieces.
Melt the butter in a frying pan and fry the mushrooms and onion until softened, adding pepper and salt to taste.
Stir in the vermicelli and cook in the mushroom juice until tender.
Assemble and bake
Let the mixture cool, then line tartlet tins with whole-wheat crust.
Fill the tins with the mushroom mixture, cover with crust, and press the edges together.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main filling and release juices that cook the vermicelli until tender.
- Vermicelli
- Absorbs the mushroom juices and thickens the filling so it holds its shape in the tart.
- Butter
- Adds fat for frying the mushrooms and onion, carrying flavour and aiding browning.
- Onion
- Adds aroma and savoury sweetness as it softens in the butter.
The step that matters
Cooking the vermicelli in the mushroom juice. The filling must be cooked until the vermicelli is fully tender and the liquid has reduced, because undercooked starch stays firm and any leftover liquid can soften the crust and make the tartlets soggy during baking.
Swap the onion
How well each one fits the dish's main ingredients (mushroom, butter, pepper):

- Onionthe original
Fit is the average pairing score against mushroom, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
