Gingerbread Nuts

Oven, in the book's wordsA very moderate oven

Ingredients

2 pounds all-purpose flour
2 cups treacle (molasses)
¾ pound butter (1½ cups)
¾ pound moist sugar (1½ cups)
½ pound candied peel, chopped
2 ounces ground ginger
½ ounce ground caraway seeds

Directions

The book says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

Cream the butter in a large bowl.
Add the flour and spices, then mix in the sugar and candied peel.
Stir in the hot treacle until well combined.
Cover the mixture and let it rest for 1 hour.

Shape and bake

Roll out the dough and cut into shapes.
Bake on baking sheets in a moderate oven at 350°F (175°C) for 10 minutes.

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

All-purpose flour: Provides the structure that holds the dough together after baking.
Treacle (molasses): Adds moisture, dark color, and deep sweetness with a slightly bitter edge.
Butter: Adds fat for tenderness and rich flavor in the dough.
Moist sugar: Adds sweetness and moisture, and helps the cookies brown.
Ground ginger: Contributes the warm, spicy aroma that defines the cookie.

The step that matters

Resting the dough for 1 hour. Resting lets the flour fully hydrate and the dough firm up, which makes it easier to roll and cut cleanly and helps the cookies keep their shape in the oven.

Swap the ginger
