Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate 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
Cream the butter and sugar together.
Add the beaten eggs, melted chocolate, and sifted flour mixed with baking powder.
Shape and bake
Roll out the dough to 1 inch thick.
Cut out shapes with a doughnut cutter.
Dust with powdered sugar and bake for 10 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the dough a tender, rich texture.
- Eggs
- Bind the dough and add structure and richness as they set in the oven.
- Unsweetened chocolate
- Adds deep chocolate flavour and colour to the dough.
- Flour
- Forms the structure of the dough as its proteins set during baking.
- Baking powder
- Releases gas in the oven, helping the jumbles rise and become light.
- Sugar
- Sweetens the dough and, creamed with butter, helps create a tender crumb.
The step that matters
Cream the butter and sugar together. Beating butter and sugar traps air in the fat, which helps the dough stay light. Under-creaming leaves a denser jumble, while over-softened butter can make the dough greasy and spread.
