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 Wafers
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.
Make the date filling
Stone the dates and boil them with 1 cup of sugar and 1 cup of water until smooth.
Let the date mixture cool.
Make the dough
In a bowl, combine oatmeal, flour, 1 cup of sugar, and salt.
Work in the lard and butter until the mixture resembles pie crust.
Moisten the mixture with sour milk and dissolved baking soda.
Roll the dough very thin.
Assemble and bake
Spread half of the dough with the date pulp, then fold the other half over.
Cut into squares.
Bake on an upside-down pan at 350°F (175°C) until golden.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Forms the bulk of the dough, giving a hearty, tender-chewy texture.
- Flour
- Provides structure so the dough can be rolled thin and hold its shape.
- Lard and butter
- Fat that is worked into the flour, tenderizing the dough and giving a crumbly, flaky texture.
- Sour milk
- Acidic liquid that moistens the dough and reacts with the baking soda.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lightens the dough and aids browning.
- Dates or figs
- Sweet, thick pulp that forms the moist filling once cooked smooth.
The step that matters
Rolling the dough very thin. Thin dough bakes evenly and crisps, while thick dough stays doughy in the centre and does not brown properly before the filling is set.
Swap the dates
How well each one fits the dish's main ingredients (flour, butter, milk, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Datesthe original
Fit is the average pairing score against flour, butter, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
