Ginger Nuts

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 dough

Melt the syrup and butter (or lard) together.
Pour the melted mixture into the dry ingredients and work into a dough.

Shape and bake

Break off pieces the size of a nut and roll them into balls.
Flatten the balls slightly and lay them on a baking sheet.
Bake at 350°F (175°C) for 10 minutes.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour: Forms the main structure of the dough as its proteins bond with the liquid.
Syrup: Adds sweetness and moisture, and helps the cookies stay chewy.
Butter or lard: Adds fat for tenderness and richness in the dough.
Baking soda: Reacts with the acidic syrup to produce gas that lightens the cookies.
