Mayonnaise 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.

Soak and combine

  1. Soak dates in boiling water with cinnamon for a few minutes.

  2. Sift together sugar, baking soda, cocoa, and salt.

  3. Combine the dry ingredients with the soaked dates and mayonnaise (or oil and egg).

Bake and finish

  1. Fold in chopped nuts and flour until just combined.

  2. Bake in two layers at 350°F (175°C) until a toothpick comes out clean.

  3. Cool and frost with whipped cream.

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

What each ingredient does

Dates
Add sweetness and moisture, and break down into the batter when soaked.
Sugar
Adds sweetness and helps keep the cake moist and tender.
Baking soda
Lifts the batter as it reacts with acidic ingredients and releases carbon dioxide.
Cocoa
Provides chocolate flavor and a deep brown color.
Mayonnaise
Supplies fat and egg, adding moisture and a tender crumb.
Flour
Provides the structure that holds the cake together once baked.

The step that matters

Fold in the flour and nuts until just combined. Overmixing develops gluten in the flour, which makes the cake tough and dense instead of tender.

Swap the cocoa

How well each one fits the dish's main ingredients (dates, sugar, cinnamon, egg, nuts, flour):

  4. Cocoathe original

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