Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Baked Custard and Floating Island
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Preheat the oven to 300°F (150°C).
In a bowl, combine scalding milk, beaten eggs, sugar, and vanilla extract.
Pour the mixture into a baking dish.
Bake in the preheated oven until set.
Finish and serve
Once cooled, top with floating island and garnish with strips of currant jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Coagulate as they heat, setting the liquid into a sliceable custard.
- Milk
- Provides the liquid base and creamy body that the eggs set into.
- Sugar
- Sweetens the custard and softens its set texture slightly.
The step that matters
Bake until just set. Egg proteins set as the custard heats. Overbaking tightens them too far, causing a grainy texture and weeping liquid. Pull it out while the centre still wobbles slightly.
Swap the currant
How well each one fits the dish's main ingredients (milk, egg, sugar, vanilla):
- Figfits better
- Peachfits better
- Blueberryfits better
- Currantthe original
Fit is the average pairing score against milk, egg, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
