Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Boiled Molasses Chips

Oven, in the book's wordsA quick oven

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.

Make the dough

  1. Boil the molasses and butter together for 5 minutes.

  2. Remove from heat, add the baking soda and ginger, and sift in enough flour to form a dough.

Shape and bake

  1. Roll the dough as thin as paper and cut into strips about 4 inches long and 1½ inches wide.

  2. Bake in a 400°F (200°C) oven until done.

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

What each ingredient does

Molasses
Provides sweetness, dark color, and moisture, and helps the chips brown in the oven.
Butter
Adds fat for richness and a crisp, tender texture.
Baking soda
Reacts with the molasses to lighten the dough and encourage browning.
Ginger
Adds warm, spicy aroma that defines the flavor of the chips.
Flour
Gives the molasses and butter enough structure to roll out into a dough.

The step that matters

Rolling the dough paper-thin. Thin dough dries out and crisps quickly in the oven, while thick dough holds moisture and bakes soft and chewy. An even, very thin roll is what gives the chips their crispness.

Swap the ginger

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

  1. Cinnamonfits better
  2. Jalapenofits better
  3. Nutmegfits better
  4. Gingerthe original

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