Why it works: Oats and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,532 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Date Cookies
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Boil dates, water, and sugar together, then let cool.
Make the dough
Cream together brown sugar and butter in a bowl.
Add eggs, flour, rolled oats, vanilla, cream of tartar, and baking soda dissolved in hot water. Mix until combined.
Shape and bake
Roll out the dough, place a little date mixture on one cookie, and top with another cookie.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dates
- Provide the sweet, moist filling that sets inside the cookies.
- Butter
- Adds fat for tenderness and rich flavor in the dough.
- Eggs
- Bind the dough and add structure as it bakes.
- Flour
- Forms the main structure of the cookie dough.
- Rolled oats
- Add chewy texture and a toasty, nutty flavor.
- Baking soda
- Reacts with the acidic cream of tartar and brown sugar to help the cookies rise and brown.
The step that matters
Shape and bake. Too much filling or a dough that is too thin can cause the date mixture to leak out while baking. Keep the filling to a small amount and seal the edges well so the cookies hold their shape and bake evenly.
Swap the dates
How well each one fits the dish's main ingredients (sugar, butter, egg, flour, oats, vanilla, cream):

Fit is the average pairing score against sugar, butter, egg, flour, oats, vanilla, cream. Candidates are from the same food group and used in at least 100 recipes.
