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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 400°F (200°C).
In a bowl, mix cornmeal, flour, salt, and baking powder.
In another bowl, beat the sugar and egg yolks until light.
Add the milk to the egg yolk mixture, then combine with the dry ingredients.
Gently fold in the beaten egg whites.
Bake and serve
Pour the batter into round jelly tins.
Bake for about 20-25 minutes until golden.
Serve hot with butter or salted cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and bind the batter, while whipped whites add lift and a light texture.
- Cornmeal
- Gives the cake its grainy texture and yellow colour.
- All-purpose flour
- Provides the main structure that holds the cake together.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- White sugar
- Adds sweetness and helps the golden browning of the crust.
- Milk
- Adds moisture and hydrates the flour and cornmeal to form the batter.
The step that matters
Folding in the egg whites. Whites hold air only when beaten to soft peaks. Folding gently keeps that air in the batter, so the cake rises lightly instead of turning dense.
