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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, mix the cornmeal, flour, sugar, salt, and baking powder.
In another bowl, beat the egg and add the milk.
Make and bake
Combine the wet and dry ingredients until just mixed.
Pour the batter into a greased baking dish.
Bake for 25-30 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure that holds the batter together as it bakes.
- Cornmeal
- Gives the cake its coarse, grainy texture and golden colour.
- Egg
- Binds the batter and adds structure and richness.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Milk
- Hydrates the dry ingredients and adds moisture to the batter.
- Sugar
- Adds sweetness and helps the crust brown as it bakes.
The step that matters
Combine the wet and dry ingredients until just mixed. Overmixing develops gluten in the flour, which makes the cake tough and dense. Stir only until no dry streaks remain, leaving small lumps.
