Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a rather moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Melt the butter in the cream.
Stir the mixture into the hot mashed potatoes.
Add salt, white pepper, and beaten eggs.
Mix in enough flour to form a dough.
Roll out the dough and cut into thin biscuits.
Bake and serve
Bake in a moderate oven at 350°F (175°C) until golden.
Serve hot with butter.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add structure so the puffs hold their shape.
- Flour
- Gives the dough enough body to roll out and cut into shapes.
- Mashed potatoes
- Form the bulk of the dough and provide a soft, tender texture.
- Butter
- Adds richness and fat for flavor and tenderness, and helps browning in the oven.
- Cream
- Adds moisture and richness to the dough.
The step that matters
Mix in enough flour to form a dough. Too little flour leaves the dough too sticky to cut, while too much makes the biscuits dense and tough. Add flour gradually until the dough is just workable.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, cream, potato, egg, flour):
- Nutmegfits better
- Capersfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against butter, cream, potato, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
