Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Mother's 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.
Prepare
Preheat the oven to 350°F (175°C).
Prepare a pie crust as you would for any pie.
Make and bake the pie
In a bowl, mix the grated lemon rind, lemon juice, sugar, flour, eggs, and syrup until well combined.
Pour the lemon mixture into the pie crust and cover with a top crust.
Bake until the crust is golden and the filling is set.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Set the filling so it firms up when baked.
- Flour
- Thickens the lemon filling so it holds its shape when sliced.
- Sugar
- Sweetens the filling and balances the sharpness of the lemon.
- Lemon juice
- Provides the acidity and bright lemon flavour of the filling.
- Syrup
- Adds sweetness and moisture to the filling.
The step that matters
Bake until the filling is set. Egg proteins coagulate as they heat, firming the filling. Pulling the pie too early leaves it runny, while overbaking can make it dry and cracked.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, flour, egg, syrup):

- Figfits about as well
Fit is the average pairing score against sugar, flour, egg, syrup. Candidates are from the same food group and used in at least 100 recipes.
