To Jill Preserved Oranges

Oven, in the book's wordsA very slow oven

Ingredients

Directions

The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the filling

  1. Grate the Naples biscuits and mix with the blanched almonds, beaten egg yolks, sugar, warmed butter, and orange‑flower water.

Fill and bake

  1. Fill the preserved oranges with the mixture.

  2. Bake in a slow oven at 300°F (150°C).

  3. If desired, sift sugar over the filled oranges to frost them.

  4. Otherwise, wipe them clean.

  5. Do not bake the oranges.

  6. Fill them once cooled.

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

Egg yolks
Set the mixture into a soft, custard-like structure as they cook.
Naples biscuits
Provide body and crumb, soaking up the liquid to thicken the filling.
Butter
Adds fat for richness and a smooth, tender texture.
Blanched almonds
Add texture and a nutty richness to the filling.
Orange-flower water
Adds a floral citrus aroma that suits the preserved oranges.

The step that matters

Bake in a slow oven at 300°F (150°C). Gentle, moderate heat lets the egg yolks set the filling slowly and evenly. A hot oven can overcook the eggs, making the custard grainy, curdled, or dry.
