Lemon 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 batter

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

  2. Beat the egg yolks until creamy.

  3. Add the sugar and beat until stiff.

  4. Gently fold the yolk mixture into the stiffly beaten egg whites.

  5. Sift half the flour over the mixture.

  6. Fold the sifted flour into the mixture.

  7. Add the remaining flour.

  8. Pour the batter into un-oiled cake pans to make two layers.

  9. Bake for 20 minutes.

Make the filling

  1. Beat the egg white with the grated lemon rind, lemon juice, and lemon essence.

  2. Thicken the filling with confectioners' sugar.

  3. Alternatively, mix water, confectioners' sugar, and nut butter until creamy.

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

What each ingredient does

Eggs
Whipped whites trap air and yolks add richness, setting with heat to give structure.
Flour
Forms the gluten network that sets the cake's crumb once baked.
Sugar
Sweetens the batter and helps the beaten eggs hold a stiff, stable foam.
Lemon juice
Adds acidity and bright lemon flavour to the batter and filling.

The step that matters

Folding the yolk mixture into the whites. Fold the yolk mixture into the stiffly beaten whites gently. Vigorous stirring knocks out the air trapped in the whites, which is what lifts the cake, so a heavy hand leaves it dense.

Swap the lemon

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

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