Why it works: Corn and lemon are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,927 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Lemon Cake
Ingredients
Directions
Cook the cornstarch base
Dissolve the cornstarch in cold water.
Add boiling water and salt, then boil for several minutes.
Make the icing
In a deep bowl, combine confectioner's sugar and lemon juice.
Add the cornstarch mixture by the teaspoon until the paste is thin enough to spread easily.

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.

Sugar and lemon 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
- Cornstarch (in the method)
- Thickens the liquid into a smooth paste that holds its shape when spread.
- Confectioner's sugar
- Provides sweetness and bulk, forming the body of the icing.
- Lemon juice
- Adds tartness and flavor that balances the sweetness of the sugar.
The step that matters
Add the cornstarch mixture by the teaspoon. Cornstarch thickens as it is heated and hydrated, so adding it gradually lets you control the consistency and avoid a stiff or lumpy paste.
Swap the lemon
How well each one fits the dish's main ingredients (corn, sugar):
- Vanillafits better
- Coconutfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against corn, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
