Orange Filling for Cake

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the filling

  1. Mix 2 tablespoons of flour with ½ cup of cold milk.

  2. Pour ½ pint of boiling milk over the flour mixture.

  3. Stir constantly over heat until thick and smooth.

  4. Remove from heat and add 2 egg yolks, 4 tablespoons of sugar, grated orange rind, and 3 tablespoons of orange juice.

Cool and use

  1. Let the mixture cool for at least 1 hour before using between cake layers.

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

What each ingredient does

Flour
Thickens the milk into a smooth, spreadable custard as it cooks.
Egg yolks
Add richness and help set the filling as it thickens with heat.
Sugar
Adds sweetness and balances the tartness of the orange juice.
Orange juice
Adds bright citrus flavour and some acidity to the custard.

The step that matters

Stirring constantly over heat until thick. Flour thickens milk by swelling its starch as it heats, but the mixture can lump or scorch if left unstirred. Constant stirring keeps the heat even so the filling becomes smooth.

Swap the orange

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

  1. Vanillafits better

  3. Figfits better
  4. Orangethe original

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