Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Oat Meal 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 the batter
Soak the oat meal in cold water and a little salt overnight.
In the morning, add sour milk (or milk and cream), sugar, and baking soda.
Mix in enough flour to create a stiff batter.
Bake
Preheat gem pans and bake in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oat meal
- Soaked overnight, it softens and gives the gems their hearty, chewy body.
- Sour milk
- Its acidity reacts with the baking soda to lift the batter and add tang.
- Baking soda
- Reacts with the acid in the sour milk to produce gas that makes the gems rise.
- Flour
- Adds structure so the batter holds its shape as it bakes.
- Sugar
- Adds sweetness and helps the gems brown at the edges.
The step that matters
Preheat the gem pans before baking. Hot pans start the batter cooking on contact, helping the gems rise quickly and form a crisp, well-set crust instead of spreading or sticking.
