Why it works: Walnut and dates 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 says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove stones from the dates and leave them whole.
Add the walnut halves and sift the sugar over the mixture.
Make the batter
Beat the egg yolks and mix them with the dates, nuts, and sugar.
Beat the egg whites and fold them into the mixture.
Sift the flour with the baking powder and mix thoroughly.
Bake
Line two bread tins with buttered wax paper, pour in the mixture, and bake for 45 minutes at 300°F (150°C).

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks bind the batter and whites, folded in, lighten its structure.
- Baking powder
- Releases gas in the oven, helping the cake rise and turn light.
- Flour
- Provides starch and gluten that set during baking, giving the cake its structure.
- Dates
- Add moisture and natural sweetness, keeping the cake soft and rich.
- Walnut halves
- Add fat, texture and a nutty flavour to the crumb.
The step that matters
Folding in the egg whites. Whipped egg whites hold air that makes the cake light. Stirring them in vigorously knocks that air out, so fold gently with a spatula until just blended.
Swap the walnut
How well each one fits the dish's main ingredients (dates, sugar, egg, flour):
- Almondfits better
- Chestnutfits better
- Mixed nutsfits about as well
- Walnutthe original
Fit is the average pairing score against dates, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
