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 hot 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) and grease gem irons.
Make and bake the batter
In a bowl, combine the beaten egg, melted butter, salt, sour milk, and baking soda.
Gradually add the graham flour, mixing until smooth.
Pour the batter into the prepared gem irons and bake for about 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Binds the batter and adds structure as it sets in the oven.
- Sour milk
- Its acidity reacts with the baking soda to produce gas that lifts the batter.
- Baking soda
- Reacts with the acid in the sour milk to make the gems rise.
- Graham flour
- Provides the bulk and the coarse, wholesome texture of the gems.
- Melted butter
- Adds fat for tenderness and a richer flavour.
The step that matters
Pour the batter and bake promptly. Baking soda starts reacting as soon as it meets the acidic sour milk, so the batter should go into the hot gem irons right away to trap the rising gas before it escapes.
