Rocky Mountain 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 sweet milk and mix well.

  4. In a separate bowl, combine the flour and baking powder.

  5. Gradually add the dry ingredients to the wet mixture, mixing until smooth.

  6. Fold in the egg whites gently until just combined.

Bake and decorate

  1. Pour the batter into a greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean.

  2. Once cooled, top the cake with icing and decorate with chopped raisins, figs, and nuts to represent mountains and valleys.

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

What each ingredient does

Butter
Creaming with sugar traps air and gives the cake a tender, rich crumb.
Sugar
Creaming with butter adds air and sweetness, and helps the cake brown.
Flour
Provides the structure that holds the cake together as it bakes.
Egg whites
Folded in gently, they add lift and help set the crumb structure.
Baking powder
Releases gas in the batter, causing the cake to rise in the oven.

The step that matters

Fold in the egg whites gently. Overmixing knocks out the air whipped into the egg whites, so the cake rises less and turns dense.

Swap the nuts

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

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Nutsthe original

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