Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a bowl, mix the rolled oats, flour, brown sugar, butter, lard, sour milk, and baking soda until well combined.
Make the filling
For the filling, combine the dates, brown sugar, and hot water in a saucepan and cook until the dates are soft.
Assemble and bake
Roll out the dough quite thin and spread the date filling between two layers of dough.
Bake in the preheated oven until golden brown, then let cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Gives the dough structure so it holds together when rolled and layered.
- Rolled oats
- Adds chewy texture and body to the dough.
- Butter
- Its fat coats the flour, adding richness and tenderness to the dough.
- Sour milk
- Its acidity reacts with baking soda and helps tenderize the dough.
- Baking soda
- Reacts with the sour milk to produce gas that lifts the dough.
- Dates
- Soften into a sweet, moist filling that flavours the cake.
The step that matters
Cooking the date filling until soft. Dates must break down fully into a smooth, spreadable paste. Undercooked dates stay firm and lumpy, so they won't spread evenly or blend with the dough during baking.
Swap the dates
How well each one fits the dish's main ingredients (oats, flour, sugar, butter, milk):
- Vanillafits better
- Raisinfits better
- Blueberryfits better
- Datesthe original
Fit is the average pairing score against oats, flour, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
