Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Graham Gems
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 oven to 400°F (200°C).
Grease the baking irons well and heat them.
Make the batter
In a bowl, mix sour milk, sugar, egg, baking soda, and melted butter.
Gradually add Graham flour until the mixture thickens.
Bake
Pour the mixture into the hot irons and bake until golden.

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 produce gas that lifts the batter.
- Baking soda
- Reacts with the acid in the sour milk to leaven the gems and help them rise.
- Egg
- Binds the batter and adds structure as the gems set in the oven.
- Graham flour
- Thickens the batter and forms the body of the gems.
- Melted butter
- Adds fat for tenderness and a rich flavor.
- Sugar
- Sweetens the batter and helps the surface brown as it bakes.
The step that matters
Heating the irons before pouring the batter. Pouring batter into hot, greased irons starts the crust setting immediately, so the gems rise well and release cleanly instead of spreading or sticking.
