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).

Mix the batter

  1. In a bowl, combine bran, flour, molasses, baking soda, and salt.

  2. Add milk gradually until the mixture is moderately stiff.

Bake

  1. Drop spoonfuls of the mixture into gem tins.

  2. Bake in the preheated oven 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.

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

What each ingredient does

Bran
Adds fiber-rich bulk and a hearty, coarse texture to the gems.
Flour
Provides the main structure that holds the gems together as they bake.
Molasses
Adds sweetness and depth of flavor, and helps the gems brown.
Baking soda
Reacts with the molasses to release gas, helping the gems rise.
Milk
Hydrates the flour and bran so the batter forms a moderately stiff dough.

The step that matters

Adding the milk gradually. Bran and flour absorb liquid at different rates, so adding milk slowly lets you reach a moderately stiff mixture. Too much liquid makes the gems spread and turn heavy, while too little leaves them dry and crumbly.

Swap the nuts

The recipe marks nuts as optional. How well each one fits the dish's main ingredients (flour, molasses, milk):

  1. Almondfits better
  2. Chestnutfits better
  3. Beansfits about as well
  4. Nutsthe original

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