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 ↓
Apple Tart
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream together the butter and sugar with the egg.
Mix in the flour until combined.
Roll out the dough and make a double crust in a round pie dish.
Bake
Bake in a moderate oven at 350°F (175°C) until golden.
Fill and serve
Once cooled, fill the tart with the cooked apples.
Top with whipped cream and serve cold.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that makes the dough rich and tender.
- Sugar
- Sweetens the dough and helps it brown in the oven.
- Egg
- Binds the dough and adds structure as it sets.
- Flour
- Builds the structure that holds the crust together.
- Apples
- Provide the fruit filling and its flavor.
The step that matters
Let the tart cool before filling it. A hot crust can soften and turn soggy when the filling is added, and warm fillings can melt the topping. Cooling lets the crust set firmly so it holds its shape and texture.
Swap the apple
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, cream):

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