Amber Custard

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

Prepare

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

Make the custard

  1. In a bowl, beat the eggs and mix in the butter until smooth.

  2. Add the sugar, plum jelly, sweet milk, and flour, and stir until well combined.

  3. Pour the mixture into a baking dish.

Bake

  1. Bake for about 30-40 minutes, or until set.

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

What each ingredient does

Eggs
Set the custard into a firm, sliceable structure as they cook.
Butter
Adds richness and a smooth, tender texture to the custard.
Sugar
Sweetens the custard and helps it brown lightly in the oven.
Plum jelly
Adds fruit sweetness, colour and body to the custard.
Sweet milk
Provides liquid that gives the custard a soft, creamy texture.
Flour
Thickens the custard slightly so it holds its shape when set.

The step that matters

Bake until set. Eggs continue to firm as they cool, so pulling the custard too early leaves it runny in the centre, while overbaking makes it dry and grainy. Check for a set centre rather than relying only on the time.

Swap the plum

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

  1. Vanillafits better
  2. Raisinfits better
  3. Figfits better
  4. Plumthe original

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