Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Preheat your oven to 400°F (200°C).

Make and bake the cookies

In a bowl, mix together the sugar and baking powder.
Add the milk and well-beaten eggs to the mixture.
Fold in the chopped hickory nut meats.
Drop spoonfuls of the batter onto a baking sheet.
Bake in the preheated oven until golden.

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 as they set in the oven.
Baking powder: Releases gas in the batter so the cookies rise and turn light.
Sugar: Sweetens the cookies and helps them brown as they bake.
Hickory nut meats: Add nutty flavour and a bit of texture to the batter.
