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 ↓
Stuffed Potatoes
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potatoes
Bake the potatoes until soft.
Cut them in half lengthwise and scoop out the insides.
Fill and top
Mash the potato smooth, adding butter, cream, salt, and pepper.
Fill the potato skins with the mixture.
Beat the egg whites and spread a spoonful over each potato half.
Bake and serve
Bake in a slow oven at 300°F (150°C) for 45 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large potatoes
- Provide the starchy base that mashes smooth and holds the filling inside the skins.
- Butter
- Adds fat and richness, making the mashed potato smoother and more flavorful.
- Cream
- Adds moisture and richness, keeping the mashed potato soft and creamy.
- Egg whites
- Set during baking to form a light, lightly browned topping over the filling.
The step that matters
Beat the egg whites and spread a spoonful over each potato half. Egg whites need to be beaten to a stiff foam so the topping holds its shape and sets lightly in the oven rather than running into the filling.
Swap the potato
How well each one fits the dish's main ingredients (butter, cream, pepper, egg):

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