Why it works: Flour and cinnamon are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 17,341 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Vinegar Pie
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.
Make the filling
In a bowl, combine sugar, vinegar, flour, butter, cinnamon, and water, and mix until thick.
Bake
Pour the mixture into a pie crust.
Bake at 350°F (175°C) until set, similar to a custard pie.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Sugar
- Provides sweetness and helps the filling thicken and set as it cooks.
- Vinegar
- Supplies the sharp acidity that defines the pie's flavour and balances the sugar.
- Flour
- Thickens the liquid filling so it sets into a sliceable custard-like texture.
- Butter
- Adds richness and fat, giving the filling a smoother mouthfeel.
The step that matters
Bake until set. Starch from the flour thickens as it heats, and the egg-free filling firms only once it reaches a set state. Pulling it too early leaves a runny pie, while overbaking can make it weep or crack as it cools.
“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.
