Why it works: Wheat and corn match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 465 recipes. Both carry hexanal, which smells green, grassy. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Mix cornmeal, wheat flour, corn starch, salt, and enough water or milk to wet thoroughly.
Let the mixture sit overnight.
Mix and bake
In the morning, add egg, baking soda, sugar, and melted butter, then beat well.
Bake immediately in a hot oven at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fine yellow cornmeal
- Provides the main body and corn flavour of the cake.
- Egg
- Binds the batter and adds structure as it sets in the oven.
- Baking soda
- Reacts with the batter to produce gas, helping the cake rise and lighten.
- Wheat flour
- Adds gluten-forming protein that gives the cake a little more structure.
- Melted butter
- Adds fat for tenderness and richness in the crumb.
The step that matters
Bake immediately in a hot oven. Baking soda starts releasing gas as soon as it meets the wet batter, so delaying the bake lets much of the lift escape. A hot oven sets the structure quickly while the gas is still expanding.
“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.
