Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make and bake the batter
In a bowl, mix flour, cornmeal, sugar, salt, and baking powder thoroughly.
Beat the egg, add the milk, and stir into the dry mixture.
Pour the batter into a shallow pan and bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Egg
- Binds the batter and adds structure and richness as it sets.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Milk
- Adds moisture and hydrates the flour so the batter can form.
- Sugar
- Adds sweetness and helps the crust brown during baking.
- Cornmeal
- Adds a coarser texture and a mild corn flavour to the crumb.
The step that matters
Bake until golden brown. Baking too briefly leaves the centre wet and gummy, while overbaking dries the crumb. Browning comes from the Maillard reaction and sugar caramelisation, so colour is a useful sign of doneness.
“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.
