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 oven to 400°F (200°C).

  2. In a bowl, mix the Graham flour, wheat flour, sour milk, water, molasses, salt, and baking soda until well combined.

Bake

  1. Fill hot gem pans with the batter.

  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

Graham flour
Provides the bulk and structure of the gems, with a nutty, coarse texture.
Wheat flour
Adds gluten for structure, helping the gems hold their shape and rise.
Sour milk
Its acidity reacts with the baking soda to produce gas, lifting the batter and tenderizing it.
Baking soda
Reacts with the acid in the sour milk to release carbon dioxide, causing the gems to rise.
Molasses
Adds sweetness, moisture, and a deep brown color to the gems.

The step that matters

Fill hot gem pans with the batter. Pouring batter into hot pans starts the setting and rising immediately, so the gems puff and form a crisp edge. Cold pans let the batter spread and bake less evenly. Batter should go in promptly after mixing, since the baking soda starts reacting as soon as it meets the acidic sour milk.
