Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Coffee Bread
Ingredients
Directions
Make the dough
Scald the milk; add butter, sugar, and salt; cool to lukewarm.
Add dissolved yeast and enough flour to make a thick batter.
Let rise overnight.
In the morning, add the beaten egg and raisins. Adjust flour to achieve a stiff batter.
Shape and top
Spread the batter in a buttered baking pan; cover and let rise.
When light, brush the top with beaten egg.
For the topping, melt 1 ½ tablespoons butter, then mix in sugar, cinnamon, and flour.
Spread the topping over the batter.
Bake
Bake in a moderate oven at 375 °F (190 °C) for 45 to 60 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the batter, and adding more firms it into a stiff dough.
- Yeast
- Produces gas during the long rise, leavening the bread so it becomes light and airy.
- Egg
- Adds structure and richness, and the brushed egg helps the top brown evenly.
- Butter
- Adds fat for tender texture and flavor, and melted butter makes the topping cohesive.
- Milk
- Provides moisture and softness to the dough, and its proteins help browning.
- Sugar
- Feeds the yeast and sweetens the bread, and it helps the topping caramelize as it bakes.
The step that matters
Let the batter rise until light before topping and baking. The yeast needs time to produce gas and build a light, airy crumb. Baking before the batter has risen enough gives a dense result that may not rise well in the oven.
