Why it works: Apple and clove are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,774 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Apple Tart
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the pastry
Preheat the oven to 300°F (150°C).
Rub the butter into the flour until crumbly.
Add water gradually to form a soft dough.
Fill the dish
Place the quartered apples in a dish.
Add cloves to the apples.
Add lemon zest to the apples.
Pour ½ cup of water over the apples.
Sweeten the apples with sugar to taste.
Assemble and bake
Moisten the edge of the dish with a mixture of egg yolk and water.
Roll out a border of paste and place it on the edge.
Roll out the remaining paste to cover the dish.
Trim excess paste from the dish.
Crimp the edges of the dish.
Make small holes in the top for steam to escape.
Brush the top with the egg wash.
Bake until golden brown.
Dust with powdered sugar before serving.

Flour and butter 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
- All-purpose flour
- Forms the structure of the pastry once mixed with water.
- Butter
- Rubbed into the flour to make the pastry tender and flaky.
- Cooking apples
- Provide the main filling, becoming soft and tart as they bake.
- Egg yolk
- Mixed with water to make an egg wash that browns the pastry top.
- Sugar
- Sweetens the apples to balance their tartness.
The step that matters
Make small holes in the top for steam to escape. Steam trapped under the pastry builds pressure and can lift or split the crust, so vents let it escape while the apples cook.
Swap the clove
How well each one fits the dish's main ingredients (flour, butter, apple, lemon, sugar, egg):
- Cinnamonfits better
- Nutmegfits better
- Tarragonfits better
- Clovethe original
Fit is the average pairing score against flour, butter, apple, lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
