Why it works: Mushroom and truffle are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,900 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Melt butter in a saucepan.
Add flour and cook until golden.
Stir in chopped onion.
Gradually add cream or milk, stirring constantly.
Slice mushrooms and truffles, then mix with sweetbreads.
Add salt, cayenne, and Tabasco to the mixture.
Pour in the sauce and mix well.
While hot, add butter, lemon juice, salt, pepper, and sherry.
If sauce is not thick enough, mix flour with milk and add to the sauce.
Fill cases with the mixture, sprinkle with bread crumbs, and bake at 400°F (200°C) for 15-20 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
