Why it works: Spinach and nutmeg work together. They rank in the top 5% of all ingredient pairs, and 603 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the custard
Beat the egg yolks and whites separately.
Combine the eggs, cream, spinach juice, tansey juice, Naples biscuit, sugar, white wine, and nutmeg in a saucepan.
Heat gently until just thickened.
Bake and serve
Pour the mixture into a dish lined with pastry.
Bake in a moderate oven (350°F / 175°C) until set.
Serve warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving it body and structure.
- Cream
- Adds richness and a smooth, soft texture to the custard.
- Spinach juice
- Adds green colour and a vegetable flavour to the custard.
- Naples biscuit
- Soaks up liquid and adds body, helping the custard hold its shape.
- Sugar
- Adds sweetness and balances the greens and any bitterness.
The step that matters
Heat gently until just thickened. Egg proteins set at moderate temperatures, and high heat makes them curdle and turn grainy. Stop heating as soon as the mixture thickens, since it will set further in the oven.

Fit is the average pairing score against egg, cream, biscuit, sugar, white wine, nutmeg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
