Why it works: Butter and flour 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 ↓

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.
Make the dough
Cream together the sugar and butter until light.
Add the beaten eggs and mix well.
Incorporate enough flour to form a dough.
Shape and bake
Roll out the dough to ¼ inch thick on a surface dusted with powdered sugar.
Cut into rings using a jagging iron.
Bake on buttered tins 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
- Sugar
- Sweetens the dough and, creamed with butter, helps give it a light texture.
- Butter
- Adds fat for tenderness and richness, and holds air when creamed with sugar.
- Eggs
- Bind the dough and add moisture and structure.
- Flour
- Provides the structure that lets the dough hold its shape when rolled and cut.
The step that matters
Rolling the dough to an even ¼ inch. Even thickness makes the rings bake at the same rate. Dough rolled too thin dries out and browns quickly, while thick dough may stay doughy in the centre.
“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.
