Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Mix the hot riced potatoes, salt, butter, and egg yolks in the order given.
Beat the mixture thoroughly.
Shape and bake
Transfer the mixture to a pastry bag fitted with a large rose tube.
Press the mixture into shapes on a buttered baking sheet.
Brown slightly in a 400°F (200°C) oven.
Serve
Use as a garnish for meat or fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Riced potatoes
- Form the bulk of the mixture, giving the roses body and a soft, tender texture.
- Butter
- Adds fat and richness, contributing flavor and a smoother texture to the potatoes.
- Egg yolks
- Add richness and help bind the mixture so it holds its piped shape.
The step that matters
Beat the mixture thoroughly. Thorough beating evenly distributes the butter and yolks through the hot potato, producing a smooth, cohesive mixture that holds its shape when piped and pressed.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg):
- Asparagusfits better
- Chivefits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
