Why it works: Butter and cheese are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Directions
Prepare the eggs
Hard boil the eggs, then separate the yolks from the whites.

Mix the yolks and whites, then press through a vegetable press.

Add the butter and grated cheese, and beat until smooth.
Season with salt and dry mustard if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks give the paste its rich, creamy body, while the finely chopped whites add texture.
- Butter
- Adds fat that makes the paste smooth, spreadable, and rich in mouthfeel.
- American cheese
- Adds savory flavor and helps bind the paste into a smooth, spreadable mixture.
The step that matters
Beat the butter and cheese until smooth. Fat and cheese must be fully blended into the egg mixture so the paste emulsifies evenly. Unblended pieces of butter or cheese leave lumps and a greasy, uneven texture.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (egg, butter, cheese):
- Asparagusfits about as well
- Potatofits about as well
- Chivefits about as well
- Mustardthe original
Fit is the average pairing score against egg, butter, cheese. Candidates are from the same food group and used in at least 100 recipes.
