Why it works: Pecans and dates share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and cooks put them together in 88 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Cocoa Fruit Cookies

Oven, in the book's wordsA moderate oven

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.

Make the dough

  1. Cream the butter and sugar together.

  2. Sift the flour, cocoa, baking soda, and cinnamon together.

  3. Add the well-beaten eggs to the butter and sugar mixture.

  4. Mix in the sifted dry ingredients, then fold in the dates and pecans.

Bake

  1. Drop spoonfuls of the mixture onto a well-greased biscuit pan.

  2. 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

Butter
Creams with the sugar to give the cookies richness and a tender crumb.
Eggs
Bind the dough and add structure and moisture as they set in the oven.
Flour
Provides the main structure that holds the cookies together as they bake.
Baking soda
Reacts with the acidity in the dough to help the cookies rise and brown.
Sugar
Adds sweetness and helps the cookies brown and crisp at the edges.
Dates
Add chewy moisture and natural sweetness to the cookies.

The step that matters

Creaming the butter and sugar. Beating butter and sugar traps air in the fat, which helps the cookies rise and gives them a lighter texture. Under-creamed butter yields denser, flatter cookies.
