Why it works: Cream and butter 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 ↓
Irish Potato Snow
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 potatoes
Parboil the potatoes.
Grate the potatoes when nearly cold.
Make the batter
Beat the yolks of the eggs.
Add the cream, butter, and salt or sugar to taste.
If using sugar, grate in the nutmeg.
Gently fold in the well-beaten egg whites.
Bake and serve
Bake at 400°F (200°C) for about 15 minutes.
Serve hot as a vegetable.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the dish, giving a light, grated texture once baked.
- Eggs
- Egg whites add lift and airiness, while yolks help bind the mixture and enrich it.
- Heavy cream
- Adds moisture and richness, keeping the baked dish soft and tender.
- Butter
- Adds fat for richness and flavor, and helps the dish brown lightly in the oven.
The step that matters
Gently fold in the well-beaten egg whites. Egg whites trap air that gives the dish its lightness. Stirring vigorously knocks that air out, so folding slowly keeps the mixture airy and risen when baked.
Swap the potato
How well each one fits the dish's main ingredients (egg, cream, butter, sugar, nutmeg):
- Leekfits about as well
- Sweet potatofits about as well
- Spinachfits about as well
- Potatothe original
Fit is the average pairing score against egg, cream, butter, sugar, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
