Why it works: Lemon and arrowroot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 553 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Lemon Meringue 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
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugar, then gradually mix in the lemon juice, grated peel, egg yolks, and arrowroot mixed with water.
Pour the mixture into a prepared pie crust.
Bake the pie until firm.
Make the meringue and finish
Whip the egg whites until soft peaks form.
Gradually add the powdered sugar and lemon juice to the whipped egg whites.
Spread the meringue over the baked pie.
Return the pie to the oven until the meringue is set and lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling and add richness as they set during baking.
- Egg whites
- Whipped into foam to form the airy, stable structure of the meringue.
- Butter
- Adds fat for a tender texture and rich flavor in the filling.
- Sugar
- Sweetens the filling and helps stabilize the whipped egg whites.
- Arrowroot
- Starch that thickens the filling so it sets firm when baked.
- Lemon juice
- Provides the acidity that gives the filling its bright, tart flavor.
The step that matters
Whipping the egg whites to soft peaks. Egg whites must be free of any fat or yolk and whipped gradually with sugar to form a stable foam. Under-whipped or greasy whites will weep or fail to hold the meringue's shape.

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