Treacle Tart

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 filling

  1. In a saucepan, combine golden syrup, breadcrumbs, lemon zest, lemon juice, and water.

  2. Heat gently until the mixture thickens, then remove from heat and stir in butter.

Bake and serve

  1. Pour the filling into the pie crust.

  2. Bake for 30-40 minutes until set and golden.

  3. Allow to cool before serving.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Golden syrup
Provides the sweet, rich base and the amber color of the filling.
Fresh breadcrumbs
Soak up the syrup and help the filling thicken and hold its texture.
Lemon
Adds acidity and aroma that cut through the sweetness of the syrup.
Butter
Adds fat and richness, giving the filling a smoother mouthfeel.
Pie crust
Forms the structure that holds the filling while it bakes.

The step that matters

Heat gently until the mixture thickens. Syrup scorches easily over high heat, and overheating can make the filling bitter or dark. Gentle heat lets the breadcrumbs absorb liquid evenly so the filling thickens without burning.

Swap the lemon

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

  1. Vanillafits better
  2. Apricotfits better
  3. Peachfits better
  4. Lemonthe original

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