Why it works: Dates and vanilla work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 218 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Hermit Cake
Ingredients
Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream the butter and brown sugar together.
Add the eggs one at a time, mixing well after each addition.
Stir in the chopped dates, walnuts, lemon extract, vanilla extract, and cinnamon.
In a separate bowl, mix the flour and baking soda.
Gradually add the flour mixture to the wet ingredients, mixing until combined.
Add a little water if the batter is too thick.
Bake
Pour the batter into a greased cake pan.
Bake for about 1 hour or 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
- Eggs
- Bind the batter and add structure and richness to the cake crumb.
- Butter
- Adds fat and tenderness, and carries flavor through the batter.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown and stay soft.
- Dates
- Add moisture and natural sweetness, keeping the cake tender and chewy.
- Baking soda
- Reacts with the batter's acidity to help the cake rise and lighten.
The step that matters
Adding the flour mixture. Mixing flour into the batter activates gluten, which toughens the cake if overworked. Stir only until combined so the crumb stays tender.
