Why it works: Beef and mushroom match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 3,231 recipes mention both. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: egg, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the filling
Chop the egg yolks, capers, and mushrooms.
Mix them with the anchovy paste and aspic jelly.
Assemble and serve
Cut the beef into thin slices and spread the mixture on each slice.
Roll each slice up and place on a bed of chopped aspic.
Serve with horse-radish sauce in the center and skinned tomatoes in the corners.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast beef
- Forms the wrapper that holds the filling together when rolled.
- Egg yolks
- Add richness and body to the filling mixture.
- Anchovy paste
- Adds a salty, savoury depth to the filling.
- Aspic jelly
- Binds the filling and sets into a firm, glossy base.
- Capers
- Add a sharp, briny acidity that cuts through the rich filling.
The step that matters
Rolling the beef slices. Slices must be thin and evenly spread so they roll without cracking or tearing. Cold aspic must be firm enough to hold the rolls in shape, since gelatin sets as it chills and only holds well at low temperatures.
Flavor stand-ins for the radish
How well each one fits the dish's main ingredients (beef, tomato, egg, capers, mushroom, anchovy, horse):

- Potatobetter flavor fit
- Radishthe original
Fit is the average pairing score against beef, tomato, egg, capers, mushroom, anchovy, horse. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
