Spunge Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Make the syrup

  1. Boil the sugar and water together, skimming well.

Make the batter

  1. In a bowl, beat the eggs until well mixed.

  2. Pour the boiling sugar mixture into the eggs and whisk until cold.

  3. Gradually mix in the flour and lemon peel.

Bake

  1. Pour the batter into a well-buttered and lined cake tin.

  2. Bake in a moderate oven at 350°F (175°C) for 45 minutes.

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

What each ingredient does

Eggs
Whisked eggs trap air and, once set in the oven, give the sponge its structure.
Flour
Provides the starch that sets during baking and gives the cake its body.
Loaf sugar
Sweetens the cake and, boiled into syrup, helps create a fine, tender crumb.
Lemon peel
Adds aromatic lemon oils that flavour the batter throughout.

The step that matters

Whisking the hot syrup into the eggs. Pouring in the boiling syrup while whisking cooks the egg proteins slightly and traps air. If the syrup is added too slowly or the eggs are not whisked well, the batter loses volume and the sponge may turn out dense.

Swap the lemon

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

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