Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Heavenly Pie
Ingredients
Directions
Make the meringue shell
Preheat the oven to 275°F (135°C).
Beat egg whites until foamy, then add cream of tartar and beat until stiff.
Gradually add 1 cup of sugar while continuing to beat until very stiff.
Line the bottom of a buttered 9‑inch pie plate with the meringue, hollowing out the center without spreading too close to the sides.
Bake for 1 hour, then cool.
Make the lemon filling
In a separate bowl, beat egg yolks slightly, then stir in ½ cup sugar, lemon juice, lemon rind, and a pinch of salt.
Cook over a double boiler, stirring constantly, until thick enough to mound when dropped from a spoon, about 8 to 10 minutes.
Remove from heat and cool.
Assemble and serve
Whip 1 cup of heavy cream and fold it into the lemon‑egg mixture.
Fill the meringue shell with the lemon‑egg mixture and chill in the refrigerator for about 24 hours.
Just before serving, garnish with the remaining whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten into foam, they form the airy structure of the meringue shell.
- Egg yolks
- Thicken the lemon filling as they cook, giving it a custard-like set.
- Lemon juice
- Adds acidity that gives the filling its tart flavor and helps balance the sweetness.
- Granulated sugar
- Sweetens the meringue and filling and helps stabilize the whipped egg whites.
- Heavy cream
- Whipped and folded in, it adds fat and lightness to the lemon filling.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a stable, stiffer foam.
The step that matters
Cooking the lemon-egg filling over a double boiler. Egg yolks thicken from heat but can scramble if overheated. Constant stirring and gentle double-boiler heat keep the filling smooth and set it evenly.
Swap the lemon
How well each one fits the dish's main ingredients (egg, cream, sugar):

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