Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Lemon Meringue Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Mix cornstarch and sugar in a bowl.
Add to boiling water, stirring constantly until clear.
Remove from heat and stir in butter, beaten yolks, lemon juice, and lemon rind.
Cool the mixture.
Bake the crust
Line a pie plate with the crust and prick it with a fork.
Bake the crust at 400°F (200°C) until golden.
Fill the baked crust with the lemon mixture.
Make the meringue and bake
In a clean bowl, beat egg whites until soft peaks form.
Add lemon juice, then gradually add sugar, beating until stiff peaks form.
Spread meringue over the lemon filling and bake at 350°F (175°C) until meringue is brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the lemon mixture into a sliceable filling as it cooks with the boiling water.
- Egg yolks
- Enrich and thicken the filling, adding richness and a smooth set.
- Egg whites
- Whipped into foam to form the airy structure of the meringue topping.
- Lemon juice
- Adds acidity that gives the filling its bright, tart flavour.
- Sugar
- Sweetens the filling and, when whipped with the whites, stabilises the meringue.
- Butter
- Adds fat for a smoother, richer texture in the cooked filling.
The step that matters
Cooking the filling until clear. Starch only thickens fully when it boils while stirred, so stopping early leaves a runny filling, and stirring constantly prevents lumps and scorching on the bottom of the pan.
