Burnt Sugar 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.

Make the syrup

  1. Burn ½ cup of sugar until it turns a good brown color.

  2. Carefully add ¼ cup of hot water and boil for a few minutes to create syrup.

Make and bake the cake

  1. In a bowl, cream ½ cup of butter with 1½ cups of sugar.

  2. Add 4 eggs (reserve 2 whites for frosting) and beat thoroughly.

  3. Mix in 1 cup of cold water.

  4. Sift together 2½ cups of flour and 2 teaspoons of baking powder, then add to the mixture.

  5. Stir in 1 teaspoon of vanilla extract and 3 teaspoons of burnt sugar, mixing well.

  6. Bake in three layers at 350°F (175°C).

Make the frosting

  1. For frosting, boil 1½ cups of sugar with ½ cup of water until a drop in cold water is firm.

  2. Pour the syrup over the beaten egg whites, beating constantly.

  3. Add 1 teaspoon of vanilla extract and 3 teaspoons of burnt sugar, beating until thick enough to spread.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Bind the batter and add structure and richness to the crumb.
Butter
Adds tenderness and richness through creaming with sugar.
All-purpose flour
Forms the cake's main structure once set by heat.
Baking powder
Releases gas that makes the cake layers rise.
Burnt sugar
Gives the cake its caramel flavor and brown color.

The step that matters

Beating the frosting until thick enough to spread. Beaten egg whites with hot sugar syrup form a stable foam that thickens as it cools and is beaten. Stopping too early leaves a runny frosting that will not hold its shape on the cake.

Swap the vanilla

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

  1. Raisinfits about as well
  2. Vanillathe original
  3. Figfits less well
  4. Lemonfits less well

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