Why it works: Butter and milk 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 the batter
Preheat your oven to 400°F (200°C).
In a bowl, cream together the butter and sugar.
Add the egg and sour milk, mixing well.
Stir in the baking soda and salt.
Gradually add graham flour until the batter is thick like griddle cake batter.
Bake
Spoon the batter into buttered gem tins.
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Graham flour
- Forms the structure of the batter and gives the gems their coarse, hearty texture.
- Sour milk
- Its acidity reacts with the baking soda to produce gas, helping the gems rise.
- Baking soda
- Reacts with the acidic sour milk to leaven the batter and lighten its crumb.
- Egg
- Binds the batter and adds moisture and structure as it sets in the oven.
- Butter
- Adds richness and fat, contributing tenderness and flavor to the gems.
The step that matters
Gradually add graham flour until the batter is thick like griddle cake batter.. Adding flour too quickly can make the batter stiff and lumpy, while too little leaves it thin and spreading. Stopping at a thick, pourable consistency lets the gems hold their shape and rise evenly in the tins.
