Oatmeal Biscuits

Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Oatmeal Biscuits

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Melt the butter.

Make the dough

  1. In a bowl, mix the oat flour, sugar, and baking powder.

  2. In a separate bowl, beat the egg with the cold water.

  3. Add the melted butter and egg mixture to the dry ingredients.

  4. Roll out the dough thin and cut into cakes.

Bake

  1. Bake in the preheated oven for 15-20 minutes or until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oat flour
Forms the body of the biscuits and gives them their oaty flavor and rustic texture.
Butter
Adds fat for tenderness and richness, and helps the biscuits brown as they bake.
Sugar
Adds sweetness and contributes to browning in the oven.
Baking powder
Releases gas that helps the biscuits rise and become lighter.
Egg
Binds the dough and adds structure and richness.

The step that matters

Rolling the dough thin. Thin dough bakes through evenly and crisps, while thick pieces can stay doughy in the centre. Oat flour has no gluten, so the dough is fragile and needs gentle handling to hold its shape when cut.

“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.
