Why it works: Cinnamon and vanilla match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,287 recipes. Both carry 4-methoxybenzaldehyde, which smells sweet, anise. The science ↓
Apple-custard Tart
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
Preheat the oven to 350°F (175°C).
Make the custard
In a bowl, combine the apple sauce, beaten eggs, and fresh milk.
Add vanilla flavoring if desired.
Pour the mixture into a pie crust-lined dish.
Sprinkle ground cinnamon on top.
Bake
Cut strips of the remaining crust and lay them across the top.
Bake in the preheated oven until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving it a firm, sliceable texture.
- Apple sauce
- Provides apple flavor and moisture, and sweetness to the custard.
- Fresh milk
- Adds liquid and richness that help the custard become smooth and tender.
- Pie crust
- Forms the base and edge that hold the custard while it bakes.
The step that matters
Bake until set. Eggs thicken as their proteins coagulate with heat. Pulling the tart too early leaves a runny custard, while overbaking can make it dry, grainy, or cracked.
Swap the vanilla
The recipe marks vanilla as optional. How well each one fits the dish's main ingredients (apple, sauce, egg, milk, cinnamon):
- Vanillathe original
- Pearfits about as well
- Figfits less well
- Plumfits less well
Fit is the average pairing score against apple, sauce, egg, milk, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
