Ribbon Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the batter

  1. Preheat the oven to 350°F (175°C).

  2. In a large bowl, cream together the sugar and butter. Add the flour, milk, eggs, and baking powder, and mix until smooth.

  3. Separate the batter into three equal parts.

  4. To one part, add the raisins, currants, molasses, and spices.

Bake and assemble

  1. Pour the three parts into corresponding size pans.

  2. Bake until a toothpick inserted comes out clean.

  3. Layer the dark part between the two lighter parts with a little jelly in between.

  4. Press the layers lightly together and frost if desired.

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.

Butter and flour 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

Eggs
Bind the batter and add structure as they set in the oven.
Baking powder
Releases gas during baking so the layers rise and stay light.
Butter
Creamed with sugar to trap air and add richness and tenderness.
Flour
Forms the structure that holds the cake's layers together.
Molasses
Adds dark colour and a deep, slightly bitter sweetness to the dark layer.

The step that matters

Baking until a toothpick comes out clean. Underbaked layers stay wet in the centre and can collapse or sink, while overbaking dries the crumb. Test in the centre of each layer, since the pans differ in size and depth.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better
  3. Datesfits about as well
  4. Currantthe original

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