Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Lemon Pies
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Prepare a pie crust.
Squeeze juice from the lemons and grate the rind of one lemon.
Make the filling
In a bowl, mix the lemon juice, grated rind, egg yolks, sugar, butter, and cream.
Pour the mixture into the pie crust and bake at 400°F (200°C).
While baking, beat the egg whites until stiff.
Top and finish
Spread the beaten egg whites on top of the pie and sprinkle with sugar.
Return the pie to the oven to brown the topping slightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the lemon filling while whites, beaten stiff, form a meringue topping.
- Lemons
- Juice and rind supply the sharp acidity and aroma of the filling.
- White sugar
- Sweetens the filling and helps the meringue topping stay glossy and brown lightly.
- Butter
- Adds richness and fat for a smoother, softer filling texture.
- Cream
- Adds moisture and richness, giving the filling a softer, creamier body.
The step that matters
Beating the egg whites until stiff. Whites must be whipped to stiff peaks to hold their shape and form a stable meringue. Under-beaten whites will weep or slump on the pie, and over-beaten whites turn grainy and dry.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, cream, butter):
- Vanillafits better
- Strawberryfits about as well
- Raspberryfits about as well
- Lemonthe original
Fit is the average pairing score against egg, sugar, cream, butter. Candidates are from the same food group and used in at least 100 recipes.
