Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Old-fashioned Sweetened Johnny Cake
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 the batter
In a bowl, combine sour milk, flour, sugar, baking soda, shortening, salt, and egg.
Stir in cornmeal until the mixture is as thick as loaf cake.
Pour the batter into a square baking tin.
Bake and serve
Bake until golden brown.
Serve hot with plenty of butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with baking soda to help the cake rise and gives a tender crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps the crust brown.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the batter.
- Shortening
- Adds fat that tenderises the crumb and keeps it moist.
- Egg
- Binds the batter and adds structure and richness.
- Cornmeal
- Adds a coarser texture and grainy body to the batter.
The step that matters
Stir in cornmeal until the mixture is as thick as loaf cake. Overmixing develops gluten in the flour, which makes the cake tough. Stir just until combined, and check that the batter has the thick, spoonable consistency the recipe describes so the cake bakes evenly.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, flour, sugar, egg):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Turmericfits less well
Fit is the average pairing score against milk, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
