Why it works: Corn and lemon are a kitchen classic. They rank in the top 13% of all ingredient pairs, and 1,927 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
Delicate Pie
Ingredients
Directions
Make the filling
Dissolve one tablespoon of corn starch in a little cold water.
Add one cup of boiling water to the mixture.
When cool, add one Q^'g., one lemon (rind and juice), a little salt, and one cup of sugar.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much aroma chemistry they share, and how many recipes mention both.

Sugar and lemon share little aroma chemistry, yet 53,532 recipes mention both: they likely 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
- Corn starch
- Thickens the filling as it heats, giving it a set, sliceable body.
- Lemon
- Supplies the sour, aromatic flavor and the juice that defines the filling.
- Sugar
- Sweetens the filling and balances the sourness of the lemon.
- Crusts
- Enclose the filling, giving the pie its structure and holding it while baking.
The step that matters
Let the starch mixture cool before adding the lemon and sugar. Cornstarch thickens only when it is heated and then set as it cools. Adding the acidic lemon and sugar to a very hot starch mixture can thin it and disturb how it sets, so cooling first helps the filling firm up properly.
Flavor stand-ins for the lemon
How well each one fits the dish's main ingredients (sugar, corn):
- Vanillabetter flavor fit
- Coconutbetter flavor fit
- Figbetter flavor fit
- Lemonthe original
Fit is the average pairing score against sugar, corn. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
