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).
Roll out the puff pastry and line a baking dish with it.
Make the filling
In a large bowl, combine the mashed potato, butter, and sugar until smooth.
Add the beaten eggs and cream, mixing well.
Pour the potato mixture into the pastry-lined dish.
Bake
Bake in the preheated oven until set and golden, about 30-40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potato
- Forms the body of the pudding and gives it a soft, starchy texture.
- Butter
- Adds richness and fat, contributing to a smooth, tender texture.
- Sugar
- Adds sweetness and helps the golden browning of the surface.
- Eggs
- Bind the mixture and set on baking to give the pudding its structure.
- Cream
- Adds moisture and richness, keeping the filling smooth and creamy.
- Puff pastry
- Forms a flaky crust that holds the filling in the baking dish.
The step that matters
Baking until set. Eggs thicken as their proteins coagulate when heated. Underbaking leaves the custardy filling runny, while overbaking can make it dry or curdled, so check for a firm centre and golden top.
Swap the potato
