Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Cream Sandwiches
Ingredients
Directions
Prepare the filling
Boil the eggs for 30 minutes.
Drop the eggs in ice water until cold.
Mix the yolks with butter and enough cream to create a smooth paste.
Add the grated meat, dry mustard, and cayenne pepper to the yolk mixture.
Assemble the sandwiches
Cut the bread into thin slices, removing the crusts.
Spread the mixture between two slices to form sandwiches.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks bind with butter and cream to form the smooth, spreadable filling.
- Ham or tongue
- Supplies the savoury meat flavour that makes up the body of the filling.
- Butter
- Adds richness and fat, helping the yolk filling spread smoothly.
- Cream
- Adds moisture so the yolk and butter blend into a smooth paste.
The step that matters
Chill the eggs in ice water. Plunging boiled eggs into ice water stops the cooking quickly, which keeps the yolks from turning grey-green and makes them easier to peel and crumble into a smooth paste.
Swap the mustard
How well each one fits the dish's main ingredients (ham, egg, butter, cream, pepper, bread):

Fit is the average pairing score against ham, egg, butter, cream, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
