Why it works: Vinegar and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 20,806 recipes. Both carry beta-damascenone, which smells apple, rose. 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.
Prepare
Preheat the oven to 350°F (175°C).
Line a pie plate with a rich crust.
Make the filling
In a saucepan, combine vinegar, water, and sugar; bring to a boil.
Add butter and enough cornstarch to thicken the mixture.
Flavor with lemon essence.
Bake
Pour the mixture into the pie shell and bake until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the sharp, acidic tang that defines the pie's flavour.
- Sugar
- Adds sweetness to balance the acidity of the vinegar.
- Cornstarch
- Thickens the liquid as it heats, so the filling sets when baked.
- Butter
- Adds richness and a smoother mouthfeel to the filling.
The step that matters
Thickening the filling with cornstarch. Cornstarch must be heated with the liquid to thicken. Adding it too little leaves the filling runny, while too much makes it gluey and pasty.
