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 ↓
Nut Pie
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
Preheat the oven to 300°F (150°C).
In a bowl, mix the flour, baking powder, dates, and walnuts.
In another bowl, beat the eggs separately.
Make the batter
Add the yolks to the powdered sugar, then fold in the egg whites.
Combine the egg mixture with the flour, baking powder, walnuts, and dates.
Bake and serve
Pour the mixture into a buttered pie tin and bake for 30 minutes.
Serve with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for lift, while yolks add richness and help bind the batter.
- Flour
- Provides structure so the pie holds together once the egg and nut mixture sets.
- Baking powder
- Releases gas during baking, helping the pie rise and become lighter in texture.
- Walnuts
- Add chewy, crunchy texture and a toasty, nutty flavour throughout the pie.
- Dates
- Add natural sweetness and moisture, giving the pie a soft, chewy body.
- Powdered sugar
- Sweetens the batter and dissolves smoothly, contributing to a tender crumb.
The step that matters
Folding in the egg whites. Whites hold air that gives the pie lift. Stirring or beating them in vigorously knocks that air out, leaving a dense result. Fold gently until just combined.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, dates, egg, flour):
- Almondfits better
- Chestnutfits better
- Mixed nutsfits about as well
- Walnutthe original
Fit is the average pairing score against sugar, dates, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
