An Excellent Cup 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.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, cream together the butter and powdered sugar.

Make the batter

  1. Beat in the lemon juice and rind, followed by the egg yolks and milk.

  2. Gradually add the flour, alternating with the whipped egg whites.

Bake

  1. Pour the batter into small tins or two square tins.

  2. Bake until golden and a toothpick comes out clean.

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.
Powdered sugar
Sweetens the batter and dissolves finely, giving a smooth, fine texture.
Eggs
Add structure and richness, and whipped whites add lift to the batter.
All-purpose flour
Provides the structure that holds the cake's shape as it sets in the oven.
Milk
Adds moisture and helps form a smooth, pourable batter.
Lemon juice and rind
Adds acidity and bright citrus aroma to the batter.

The step that matters

Alternating flour with the whipped egg whites. Folding gently keeps the air in the whipped whites, which gives lift. Overmixing once the flour is in develops gluten and toughens the crumb, and deflating the whites makes the cakes dense.

Swap the lemon

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

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