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 ↓
Plain Jumbles
Ingredients
Directions
The book says “a slow 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
Preheat your oven to 350°F (175°C).
In a mixing bowl, cream together the butter and sugar until smooth.
Gradually mix in the flour and rose water until well combined.
Bake and cool
Drop spoonfuls of the mixture onto a baking sheet lined with parchment paper.
Bake in the preheated oven until lightly golden, about 10-12 minutes.
Allow to cool on the baking sheet before transferring to a wire rack.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a tender texture.
- Sugar
- Adds sweetness and, creamed with butter, helps give the cookies a light crumb.
- All-purpose flour
- Provides the structure that holds the dough together as the cookies bake.
- Rose water
- Adds a floral aroma to the dough.
The step that matters
Bake until lightly golden. Baking time is short, and the cookies keep firming as they cool. Removing them once lightly golden, rather than deep brown, keeps them tender and avoids a bitter, dry result.
“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.
