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 ↓

Ingredients
Directions
Prepare the filling

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the smooth, soft bulk of the filling between the layers.
- Cream
- Adds moisture and richness, keeping the mashed potato smooth and creamy.
- Butter
- Adds fat and flavour, enriching the mashed potato texture.
- Rump steaks
- Provide the meat layer, which cooks through as the filling heats.
- Puff pastry
- Forms a crisp, flaky top that browns in the oven.
The step that matters
Bake until the pastry is golden brown and the filling is hot. Puff pastry needs a hot oven to rise and brown properly. The filling must reach serving heat so the meat is fully cooked through, which is hard to judge from the pastry alone.
Swap the potato
How well each one fits the dish's main ingredients (cream, butter):
- Potatothe original
- Onionfits about as well
- Leekfits less well
- Chivefits less well
Fit is the average pairing score against cream, butter. Candidates are from the same food group and used in at least 100 recipes.
