Coffee 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. 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 the batter

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

  2. In a bowl, cream together the brown sugar and butter.

  3. Add the flour, black molasses, and strong coffee; mix well.

  4. Fold in the seeded raisins and currants.

  5. Stir in the baking soda and spices to taste.

Bake

  1. Pour the batter into a greased baking pan.

  2. Bake for 30-40 minutes or until a toothpick comes out clean.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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

Brown sugar
Adds sweetness and moisture, and helps give the cake a soft, tender crumb.
Butter
Adds fat for richness and tenderness when creamed with the sugar.
Flour
Provides the structure that holds the cake together as it bakes.
Black molasses
Adds moisture, deep flavour and dark colour to the crumb.
Baking soda
Reacts with the acidic molasses to produce gas that helps the cake rise.

The step that matters

Stir in the baking soda and spices to taste.. Baking soda needs an acid, such as the molasses here, to react and lift the batter. Once the batter is mixed, it should go into the pan and oven promptly so the gas is not lost before baking.

Swap the currant

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

  1. Vanillafits better

  4. Currantthe original

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