Blueberry Cake

Oven, in the book's wordsA rather hot oven

Ingredients

Directions

The book says “a rather hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

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

  2. In a bowl, rub together the butter and sugar.

  3. Add the egg to the mixture and beat thoroughly.

  4. Stir in the milk.

  5. In a separate bowl, mix the flour with the nutmeg and baking powder, then add to the wet mixture.

  6. Beat quickly and vigorously, then gently fold in the blueberries.

Bake

  1. Pour the batter into buttered pans and bake for 35 minutes.

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

Flour
Provides the structure that holds the cake together as it sets.
Baking powder
Releases gas in the batter, causing the cake to rise and turn light.
Butter
Adds fat for tenderness and a rich flavor in the crumb.
Eggs
Binds the batter and adds structure and moisture as it bakes.
Sugar
Sweetens the cake and helps brown the crust while it bakes.
Blueberries
Add moisture and bursts of fruit flavor throughout the cake.

The step that matters

Folding in the blueberries. Once flour is mixed in, overworking the batter develops gluten and toughens the cake. Fold the blueberries in gently so the batter stays tender and the berries stay distributed rather than sinking.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Jalapenofits less well
  4. Capersfits less well

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