Why it works: Buttermilk and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. 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 the oven to 400°F (200°C) and grease gem pans.
Make the batter
In a bowl, mix the sour or buttermilk, baking soda, and salt.
Beat in the egg and molasses.
Add enough Graham flour to create a stiff batter. Mix thoroughly and fill the hot gem pans.
Bake
Bake for 15 minutes until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour or buttermilk
- Provides acidity that reacts with the baking soda to make the gems rise.
- Baking soda
- Reacts with the acid in the sour milk to produce gas, lightening the batter.
- Egg
- Adds structure and helps bind the batter as it sets in the oven.
- Molasses
- Adds sweetness, moisture and a deep color to the gems.
- Graham flour
- Forms the main body of the batter, giving the gems their structure and nutty texture.
The step that matters
Fill the hot gem pans. Filling preheated, greased pans and baking promptly lets the batter set quickly on contact with heat, helping the gems rise and release cleanly. Letting the batter sit lets the baking soda's gas escape before baking.
“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.
