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 good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
In a bowl, mix molasses, salt, butter, and baking soda until well combined.
Add sour milk and graham flour, stirring until just mixed.
Bake
Pour the batter into greased gem pans, filling them halfway.
Bake in a preheated oven at 400°F (200°C) 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
- Provides the bulk and structure that sets the gems as they bake.
- Sour milk
- Its acidity reacts with the baking soda to help lift the batter.
- Baking soda
- Reacts with the acidic sour milk to release gas that makes the gems rise.
- Molasses
- Adds sweetness, moisture and a deep brown color to the batter.
- Butter
- Adds fat that makes the gems tender and adds rich flavor.
The step that matters
Stir the batter until just mixed. Overmixing the flour and milk develops gluten, which makes gems tough and dense. Baking soda starts reacting with the sour milk as soon as they combine, so the batter should go into the pans and oven promptly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
