Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Molasses 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
Preheat the oven to 350°F (175°C).
Blanch and finely chop the almonds.
Mix and bake
In a large bowl, mix the flour, molasses, butter, sugar, chopped almonds, citron, baking soda, lemon rind, sweet milk, and spices until well combined.
Pour the batter into a cake mold.
Bake until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Molasses
- Adds moisture, dark color, and deep sweetness to the cake.
- Butter
- Adds fat that softens the crumb and gives a rich texture.
- Baking soda
- Reacts with the molasses's acidity to produce gas that helps the cake rise.
- Almonds
- Add texture and nutty flavor, and contribute moisture and body to the batter.
- Sweet milk
- Adds moisture and helps bind the batter into an even mixture.
The step that matters
Checking doneness with a toothpick. Molasses batters are dense and moist, so the centre can look set before it is fully baked. Testing the centre with a toothpick ensures the structure has firmed and the cake is not left gummy inside.
