Why it works: Beef and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Beat the egg yolks and finely chop the parsley.
Mix all the ingredients well together.
Bake
Brush custard cups with melted butter and press the mixture into them.
Partly fill a baking pan with boiling water and place the cups in it.
Bake in a 400°F (200°C) oven for 30 minutes.
Serve
When done, turn them out onto a heated dish.
Pour tomato sauce around and garnish with triangles or hearts of toasted bread.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chopped beef, veal, or chicken
- Provides the main body and protein structure that holds the custard together.
- Egg yolks
- Set when heated, binding the mixture and giving it a firm, custard-like texture.
- Cream or milk
- Adds moisture and richness, keeping the custard tender rather than dry.
- Butter
- Adds fat for richness and helps release the custard from the cups.
- Fresh bread crumbs
- Absorb liquid and add body, helping the mixture hold its shape.
The step that matters
Partly fill the baking pan with boiling water. The water bath surrounds the cups with gentle, even heat, so the egg sets smoothly without curdling or overcooking at the edges.
Swap the parsley
How well each one fits the dish's main ingredients (beef, butter, bread, cream, egg, sauce, mushroom):
- Nutmegfits better
- Capersfits about as well
- Tarragonfits about as well
- Parsleythe original
Fit is the average pairing score against beef, butter, bread, cream, egg, sauce, mushroom. Candidates are from the same food group and used in at least 100 recipes.
