Graham Gems

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat oven to 400°F (200°C).

Make the batter

  1. In a bowl, combine sour milk, shortening, molasses, salt, and baking soda.

  2. Stir in Graham flour until mixture is thick enough to drop from a spoon.

Bake

  1. Spoon batter into gem pans, filling them about halfway.

  2. Bake for 15-20 minutes or until golden brown.

    Shared aroma: furaneol (caramel, strawberry).

Milk and flour barely smell alike, yet cooks put them together in 78,219 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

Sour milk
Its acidity reacts with baking soda to produce gas that lifts the batter.
Baking soda
Reacts with the acidic sour milk to release carbon dioxide, causing the gems to rise.
Graham flour
Provides the bulk and structure that thickens the batter and sets the crumb.
Molasses
Adds sweetness, moisture and a deep color that aids browning.
Shortening
Adds fat that tenderizes the crumb and keeps the gems moist.

The step that matters

Stir in the Graham flour to the right thickness. The batter must be thick enough to drop from a spoon. Too thin and the gems spread and lose their shape; too much flour makes them dense. Mixing only until combined also avoids overdeveloping gluten, which would toughen the texture.
