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 ↓
Potato Souffle
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the base
Bake the potatoes until done, then burst the skins and scoop out the flesh.
Mix the potato flesh with flour, sugar, butter, and boiling cream flavored with lemon rind or cinnamon until smooth.
Add the beaten egg yolks and mix well.
Bake and serve
Whisk the egg whites to firm froth and gently fold into the mixture.
Pour the mixture into a buttered souffle dish lined with oiled paper to prevent overflow.
Bake in a preheated oven at 400°F (200°C) until set and golden.
Serve immediately after removing from the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whisked to firm froth, they trap air and lift the souffle as it bakes.
- Egg yolks
- Enrich the base and help it set into a custard-like structure.
- Potatoes
- Provide the bulk of the base, giving a light, soft body.
- Flour
- Thickens the potato mixture so it holds its shape.
- Butter
- Adds richness and fat for a tender texture and flavor.
- Cream
- Adds moisture and richness, keeping the base smooth and soft.
The step that matters
Folding in the egg whites. Whites must be whisked to firm froth and folded gently so the air bubbles survive. Overmixing deflates them, and the souffle then rises poorly and bakes dense.
Swap the potato
How well each one fits the dish's main ingredients (flour, sugar, butter, cream, lemon, egg):
- Arrowrootfits better
- Leekfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against flour, sugar, butter, cream, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
