Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Amber Custard
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the custard
In a bowl, beat the eggs and mix in the butter until smooth.
Add the sugar, plum jelly, sweet milk, and flour, and stir until well combined.
Pour the mixture into a baking dish.
Bake
Bake for about 30-40 minutes, or until set.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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 custard into a firm, sliceable structure as they cook.
- Butter
- Adds richness and a smooth, tender texture to the custard.
- Sugar
- Sweetens the custard and helps it brown lightly in the oven.
- Plum jelly
- Adds fruit sweetness, colour and body to the custard.
- Sweet milk
- Provides liquid that gives the custard a soft, creamy texture.
- Flour
- Thickens the custard slightly so it holds its shape when set.
The step that matters
Bake until set. Eggs continue to firm as they cool, so pulling the custard too early leaves it runny in the centre, while overbaking makes it dry and grainy. Check for a set centre rather than relying only on the time.
Swap the plum
How well each one fits the dish's main ingredients (egg, butter, sugar, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Plumthe original
Fit is the average pairing score against egg, butter, sugar, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
