Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Old-fashioned 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat oven to 350°F (175°C).

Make the filling

  1. In a bowl, combine the lemon juice and chopped lemon with the egg, sugar, molasses, and water. Mix well until fully combined.

  2. Add the rolled cracker and stir until incorporated.

Bake

  1. Pour the mixture into a pie crust and bake for about 30 minutes or until set.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg
Binds the filling and helps it set firm when baked.
Sugar
Adds sweetness and balances the sharpness of the lemon.
Molasses
Adds depth, dark colour and extra sweetness to the filling.
Lemon
Provides the sharp acidity and bright flavour of the pie.
Cracker
Thickens the filling and absorbs some of the liquid.

The step that matters

Bake until set. The egg proteins must coagulate to firm the filling. Underbaking leaves it runny, while overbaking can make it tough and cracked.

Swap the lemon

How well each one fits the dish's main ingredients (egg, sugar, molasses):

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Lemonthe original

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