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 ↓
Mrs. Buxton's 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).
Grease the gem pans.
Make the batter
Beat the egg well.
Add the salt.
Stir in the buttermilk or sour milk.
Add enough Graham flour to create a stiff batter.
Mix in the baking soda thoroughly.
Dip a spoon in cold water.
Bake
Drop a spoonful of batter into each gem pan.
Repeat until all pans are filled.
Bake for 30 minutes until golden brown.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 1-octen-3-ol (mushroom, earthy).
Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the batter and adds structure and richness as it sets in the oven.
- Buttermilk or sour milk
- Provides moisture and acidity that react with the baking soda to lift the batter.
- Graham flour
- Forms the body of the batter, giving the gems their structure and texture.
- Baking soda
- Reacts with the acidic buttermilk or sour milk to produce gas that makes the gems rise.
The step that matters
Mix in the baking soda thoroughly. Baking soda must be evenly distributed so it reacts with the acid in the buttermilk throughout the batter. Uneven mixing leaves pockets of bitter soda and patches that fail to rise.
“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.
