Potato Caramel 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. Cream the butter and sugar together until light and fluffy.

  3. Add the eggs one at a time, mixing well after each addition.

  4. Stir in the hot mashed potatoes and vanilla.

  5. In a separate bowl, combine the flour, baking powder, spices, and nuts.

  6. Gradually add the dry ingredients to the wet mixture, alternating with sweet milk until well combined.

  7. Fold in the grated chocolate.

Bake

  1. Pour the batter into a greased cake pan.

  2. Bake for 30-40 minutes or until a toothpick inserted in the center 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 tender, fine crumb and rich flavor.
Eggs
Add structure and richness as they set in the baked batter.
Flour
Forms the main structure of the cake as its proteins set during baking.
Baking powder
Releases gas in the batter so the cake rises and becomes light.
Mashed potatoes
Add moisture, helping the cake stay soft and moist after baking.
Granulated sugar
Sweetens the cake and helps brown its surface while creaming aerates the batter.

The step that matters

Gradually adding the dry ingredients with the sweet milk. Adding dry ingredients in alternating portions with the milk keeps the batter smooth and emulsified. Adding everything at once or overmixing can develop too much gluten, leading to a dense, tough cake.

Swap the potato

How well each one fits the dish's main ingredients (butter, sugar, chocolate, flour, nuts, clove, cinnamon):

  1. Arrowrootfits better
  2. Sweet potatofits better
  3. Capsicumfits better
  4. Potatothe original

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