Why it works: Lemon and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Novelty Lemon 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
Beat the egg yolks until light, then add lemon juice and mix well.
Add sugar and grated lemon rind to the mixture.
Place the mixture in a rounded bottom enamel bowl set in a pan of boiling water.
Keep the water boiling and whip the mixture with a wire egg beater until thick and creamy.
Remove the pan from heat but let the bowl stand in the hot water.
Make the meringue and bake
Beat the egg whites to a stiff, dry consistency and fold in the remaining ½ cup of sugar.
Divide the egg white mixture in half; fold one half into the cooked mixture and pour into a baked pie shell.
Add lemon extract to the remaining half of the egg white mixture and spread over the top of the pie.
Set the pie in the oven at 350°F (175°C) to brown lightly for about 12 minutes.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling as they cook, and whites whip into a stiff, airy meringue.
- Sugar
- Adds sweetness and helps stabilize the whipped egg whites.
- Lemon juice
- Adds the sharp acidity that gives the filling its tang.
- Grated lemon rind
- Adds aroma from the fragrant oils in the peel.
The step that matters
Whipping the filling over boiling water. Egg yolks thicken gently as their proteins set with heat. If the mixture is too cool it stays thin, and if it overheats it can curdle and turn grainy, so keep the heat steady while whipping until thick and creamy.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
