Why it works: Apple and butter are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 8,706 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Apple Grunt
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.
Prepare the crust
Make a light biscuit crust and bake it.
Turn the baked biscuit upside down on a platter and spread with butter.
Make the apple filling
Stew the apples in water until tender.
Remove from heat and mix in the egg yolk and brown sugar.
Cover the biscuit with the apple mixture.
Top and brown
Beat the egg white and spread it over the apple mixture.
Brown in the oven at 350°F (175°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Soften when stewed and form the main body of the filling.
- Egg yolk
- Enriches the apple mixture and helps it set into a custard-like texture.
- Brown sugar
- Adds sweetness and a caramel note to the apple filling.
- Butter
- Spread on the crust to add richness and moisture.
The step that matters
Brown in the oven. The beaten egg white needs enough oven heat to set and turn golden without the filling drying out. Watch the colour closely, since egg white can brown quickly once it sets.
Swap the apple
How well each one fits the dish's main ingredients (egg, sugar, butter):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
