Why it works: Corn and lemon are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,927 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Lemon Pie with a Crust
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 saucepan, combine sugar, hot water, corn starch, butter, lemon rind, and lemon juice.
Cook over medium heat for a few minutes until thickened.
Remove from heat and stir in the beaten egg and salt.
Bake and serve
Pour the filling into a pie crust and bake at 350°F (175°C) until set.
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
- White sugar
- Provides sweetness and helps balance the tartness of the lemon.
- Corn starch
- Thickens the hot liquid into a smooth, sliceable filling as it cooks.
- Lemon juice
- Adds acidity and bright lemon flavour that cuts through the sweetness.
- Egg
- Adds richness and helps the filling set when baked.
- Butter
- Adds fat for a smoother texture and richer mouthfeel.
The step that matters
Remove from heat and stir in the beaten egg. Egg proteins can scramble if the hot filling is too hot when added, which gives a grainy texture. Removing the pan from heat first lets the egg blend in smoothly and gently thicken.
Swap the lemon

Fit is the average pairing score against sugar, corn, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
