Orange Tartlets

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).

Make the filling

  1. In a bowl, combine the orange juice, grated peel, sugar, butter, lemon juice, and cornstarch mixed with cold water, then beat the mixture until smooth.

  2. Pour the filling into small pastry shells.

Bake

  1. Bake until set and lightly golden.

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

What each ingredient does

Oranges
Provide the main juice and peel flavour, along with aroma and acidity for the filling.
Sugar
Adds sweetness and balances the acidity of the citrus juice.
Butter
Adds richness and a smoother, softer texture to the filling.
Lemon juice
Adds extra acidity that brightens the flavour of the orange filling.
Cornstarch
Thickens the juice mixture so the filling sets firm when baked.

The step that matters

Bake until set and lightly golden. Cornstarch thickens as it heats, so the filling needs enough time in the oven to firm up. Pulling it too early leaves a runny centre, while overbaking can make it tough.

Swap the orange

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

  1. Vanillafits about as well
  2. Orangethe original
  3. Figfits less well
  4. Raspberryfits less well

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