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.

Prepare the batter

  1. In the evening, stir together Graham flour and cold water.

  2. In the morning, add butter, salt, and baking powder.

Bake

  1. Preheat gem irons and pour in the batter.

  2. Bake in a hot oven at 400°F (200°C) until golden.

Flour and butter 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

Graham flour
Provides the bulk and structure of the batter, with a nutty, coarse texture.
Baking powder
Releases gas as it reacts with moisture, lifting the gems as they bake.
Butter
Adds fat that tenderises the crumb and helps the surface brown.
Cold water
Hydrates the flour so it forms a thick, pourable batter.

The step that matters

Adding the baking powder in the morning. Baking powder starts releasing gas as soon as it meets moisture, so it should be stirred in shortly before the batter goes into the hot irons. If the batter sits too long after it is added, the rise weakens and the gems may bake up heavy.

Swap the walnut

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

  1. Almondfits better
  2. Macadamia nutfits better
  3. Cashew nutfits better
  4. Walnutthe original

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