Why it works: Dates and walnut work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 302 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Date 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. The book gives no cooking times either; 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).
Make the batter
In a mixing bowl, cream together the shortening and brown sugar.
Add the egg yolks and molasses, mixing well.
Stir in enough sour cream to fill the mixture.
Add the baking soda and spices, then mix thoroughly.
Gradually add the flour, mixing until combined.
Fold in the chopped dates and walnuts.
Bake
Pour the batter into a greased cake pan and bake for about 30-40 minutes, or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shortening
- Adds fat that keeps the cake tender and rich in texture.
- Egg yolks
- Add richness and help bind the batter into a stable structure.
- Baking soda
- Reacts with the acidic molasses and sour cream to lift the cake.
- Flour
- Provides the main structure that sets as the cake bakes.
- Dates
- Add moisture and natural sweetness throughout the cake.
- Molasses
- Adds moisture, deep sweetness and a darker color to the batter.
The step that matters
Gradually add the flour, mixing until combined. Overmixing once flour is in develops gluten, which can make the cake tough and dense rather than tender. Mix only until no dry flour streaks remain.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, egg, molasses, cream, flour, dates):
- Almondfits better
- Chestnutfits about as well
- Mixed nutsfits about as well
- Walnutthe original
Fit is the average pairing score against sugar, egg, molasses, cream, flour, dates. Candidates are from the same food group and used in at least 100 recipes.
