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

  1. Preheat the oven to 400°F (200°C).

Make the batter

  1. In a bowl, combine molasses, melted butter, baking soda, salt, and ginger.

  2. Stir in boiling water.

  3. Gradually add flour until you achieve a thin batter consistency.

Bake

  1. Pour the batter into thin sheets on a baking tray.

  2. Bake until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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

Molasses
Adds sweetness, dark colour and a rich, deep flavour to the batter.
Melted butter
Adds fat, which tenderises the crumb and carries flavour.
Baking soda
Reacts with the acidic molasses to produce gas, helping the batter rise and lighten.
Flour
Provides the structure that sets as the batter bakes.

The step that matters

Gradually add flour until a thin batter forms. Flour is the structure-builder, so adding it too fast or too much can leave lumps or a dense, tough result. Adding it gradually lets you reach a smooth, thin batter that bakes evenly and stays tender.

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.
