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 ↓
Wafer Jumbles
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Preheat your oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar.
Add the eggs one at a time, mixing well after each addition.
Gradually add the flour and mix until smooth.
Shape and bake
Roll out the dough thinly on a floured surface.
Cut into desired shapes and place on a baking sheet.
Bake until lightly golden, then sift powdered sugar over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that makes the jumbles rich and tender when creamed with sugar.
- Sugar
- Sweetens the dough and helps it brown lightly in the oven.
- Eggs
- Bind the dough and add structure and moisture to the cookies.
- Flour
- Provides the main structure that holds the shaped jumbles together.
The step that matters
Adding the eggs one at a time. Eggs added gradually and mixed well emulsify into the creamed butter and sugar. Adding them all at once can cause the batter to curdle or separate, leaving a grainy texture.
“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.
