Plain Custard Filling

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the custard

  1. In a bowl, combine water, sugar, flour, eggs, and oil.

  2. Beat the mixture thoroughly until well combined.

  3. Add your choice of flavoring.

Bake

  1. Pour the mixture into a crust-lined dish.

  2. Bake in the preheated oven until set.

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.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: 2-nonenal (fatty, green).

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Set the filling as they cook, giving it body and structure.
Flour
Thickens the mixture so it holds its shape rather than running.
Sugar
Adds sweetness and helps soften the set texture of the filling.

The step that matters

Bake in the preheated oven until set. Egg proteins coagulate gradually with heat. Underbaking leaves the filling runny, while overbaking can make it curdle, weep, or turn rubbery, so watch for a set centre rather than relying only on time.
