Coffee Fruix Cake

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Chop all the fruit together and set aside.

  2. Sift the cream of tartar into the flour.

  3. Dissolve the baking soda in the milk.

Make the batter

  1. In a bowl, cream the butter and sugar together until light and fluffy.

  2. Combine the flour with the butter and sugar mixture, adding more flour if necessary.

  3. In a separate bowl, beat the eggs until light and fluffy, then add to the mixture.

  4. Stir in the milk and coffee until well combined.

Bake

  1. Pour the batter into a greased cake pan and bake in a preheated oven at 350°F (175°C) until a toothpick comes out clean.

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

What each ingredient does

Butter
Creams with sugar to trap air, giving the cake a light, tender crumb and rich flavour.
Eggs
Add structure and richness, helping bind the batter and set as it bakes.
Cream of tartar
Acidifies the batter so it reacts with baking soda to help the cake rise.
Baking soda
Reacts with the acid in the batter to produce gas that lifts the cake.
Flour
Forms the main structure that holds the cake together as it bakes.

The step that matters

Dissolve the baking soda in the milk. Baking soda only leavens when it reacts with an acid. Dissolving it fully before mixing spreads it evenly, so the cake rises uniformly instead of having pockets or bitter spots.

Swap the currant
