Why it works: Buttermilk and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Maple Layer Cake
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.
Prepare
Melt the chocolate over hot water.
Dissolve the baking soda in the buttermilk.
Make the batter
Cream the butter and maple sugar together.
Add the eggs, buttermilk, and flour; mix well.
Fold in the melted chocolate last.
Bake
Bake in two layers at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Maple sugar
- Provides sweetness and moisture, and adds a caramel-like maple flavor to the cake.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Butter
- Creamed with the sugar to trap air and add tenderness and fat for flavor.
- Buttermilk
- Adds moisture and acidity, which reacts with baking soda to help the cake rise.
- Flour
- Forms the cake's structure as its proteins set during baking.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that makes the cake rise.
The step that matters
Dissolve the baking soda in the buttermilk. Baking soda must be fully dissolved so it reacts evenly with the acid in the buttermilk. Uneven pockets can leave bitter spots or uneven rising.
“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.
