Ginger Snaps

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the dough

  1. In a saucepan, boil the molasses, sugar, butter, and lard for about 10 minutes.

  2. Dissolve the baking soda in a little hot water and add the ginger.

  3. Once the mixture cools, add flour until the dough is stiff.

Roll and bake

  1. Roll out the dough as thin as possible and bake in a hot oven at 400°F (200°C).

Make the icing

  1. For the icing, beat the egg whites in a platter, gradually adding the powdered sugar until fully combined.

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

What each ingredient does

Molasses
Adds sweetness, dark color, and a chewy, moist character to the cookie.
Butter
Adds richness and flavor, and helps give the cookie a tender texture.
Lard
Adds fat that contributes to a tender, crisp texture.
Baking soda
Reacts with the molasses's acidity to lighten the dough and promote browning.
Flour
Provides structure so the stiff dough can be rolled and holds its shape when baked.
Egg whites
Whipped with powdered sugar to form a stable, glossy icing.

The step that matters

Rolling the dough thin. Thin dough bakes through and dries into a crisp snap. Thick dough stays soft and cakey, so the cookie loses its characteristic crispness.

Swap the ginger

How well each one fits the dish's main ingredients (butter, sugar, molasses, flour, egg):

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits about as well
  4. Gingerthe original

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