Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 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 flavoring, then mix well.
Gradually add enough flour to form a dough.
Shape and bake
Roll out the dough on a surface dusted with powdered sugar to ¼ inch thick.
Cut into rings using a jagged iron.
Bake on buttered baking sheets in a 400°F (200°C) oven.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Sugar
- Adds sweetness and helps the dough cream to a light, tender texture.
- Butter
- Adds fat for richness and tenderness, and creaming it traps air for a light crumb.
- Eggs
- Bind the dough and add structure and moisture to the cookies.
- Flour
- Provides structure once mixed in, forming the dough that holds the rings' shape.
The step that matters
Gradually add enough flour to form a dough. Adding flour gradually lets it blend evenly into the batter without overworking it. Too much flour or too much mixing makes the dough stiff and the cookies dense and tough.
“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.
