Coffee or Moka 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. Sift the baking powder with the flour into a bowl.

  3. Add the spices, sugar, and butter, then mix well.

  4. Make a well in the center.

  5. Pour in the syrup and add the coffee.

  6. Break in the eggs and beat well together.

  7. Mix in the other ingredients with a strong wooden spoon.

  8. If the mixture is not moist enough, add a little milk.

  9. Fold in the currants and sultanas last.

Bake

  1. Pour the batter into a long square cake pan lined with parchment paper.

  2. Bake for 1 to 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the cake's structure as the starch and gluten set during baking.
Baking powder
Releases gas during baking, helping the cake rise and turn light.
Eggs
Bind the batter and add structure and richness as they set.
Butter
Adds fat for tenderness and a rich, soft crumb.
Brown sugar
Adds sweetness and moisture, and helps the cake brown.
Strong cold coffee
Adds liquid and a deep coffee flavor to the batter.

The step that matters

Fold in the currants and sultanas last. Adding dried fruit at the end, with gentle folding, keeps the batter from being overworked. Overmixing develops gluten and can make the cake tough, and it can also let the fruit sink or break up.

Swap the currant
