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 ↓
Irish Potato Pudding
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the pudding
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the sweet cream and mix well.
Beat in the eggs one at a time, ensuring each is fully incorporated.
Fold in the mashed potatoes and grated nutmeg until well combined.
Pour the mixture into a greased baking dish.
Bake
Bake for 45-60 minutes or until set and lightly golden on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the pudding a light, rich body and fat for flavour.
- Eggs
- Set when baked, binding the mixture into a custard-like structure.
- Mashed potatoes
- Provide the bulk and soft, moist texture of the pudding.
- Sugar
- Sweetens the pudding and helps create a light, fluffy creamed base with the butter.
- Sweet cream
- Adds moisture and richness, softening the batter.
The step that matters
Beating in the eggs one at a time. Adding eggs gradually lets each one emulsify fully into the butter and sugar mixture. Adding them too quickly can cause the batter to separate or curdle, which affects the final smooth, even texture.
Swap the potato
How well each one fits the dish's main ingredients (sugar, butter, cream, egg, nutmeg):

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