Why it works: Milk and butter 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 ↓
Oatmeal Gems
Ingredients
Directions
The book gives no oven temperature. The 400°F in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Soak the oatmeal in water overnight.
Mix and bake
In the morning, add sour milk, flour, baking soda, salt, butter, and sugar to the soaked oatmeal. Mix well and adjust with more flour if too moist.
Bake in a hot (400°F/200°C), well-buttered gem pan until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Provides the bulk and chewy, hearty texture of the gems.
- Flour
- Gives the batter structure so the gems hold their shape when baked.
- Sour milk
- Its acidity reacts with the baking soda so the gems rise.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lightens the batter.
- Butter
- Adds fat for richness and helps the gems brown in the pan.
- Sugar
- Adds sweetness and helps the surface turn golden in the oven.
The step that matters
Adjust the flour in the batter. Oatmeal keeps absorbing liquid, so a batter that is too moist can spread and bake up dense. Adding flour a little at a time until it holds together gives the gems a firmer structure.
