Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
A Good Baked Custard
Ingredients
Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Boil the milk with the sugar, salt, lemon rind, and ratafia.
Beat the egg yolks and stir in the cream.
Pour the egg mixture into the milk gradually, stirring well.
Pour the mixture into a deep dish or mold.
Bake and serve
Bake at 350°F (175°C) for 10 minutes.
Let it cool, then turn it out and serve with jam around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Set the custard as they cook, giving it a firm, smooth structure.
- Milk
- Forms the liquid base that the egg yolks set into a custard.
- Cream
- Adds richness and a softer, silkier texture to the custard.
- Powdered sugar
- Sweetens the custard and helps give it a smooth, tender texture.
The step that matters
Pour the egg mixture into the milk gradually, stirring well. Adding the eggs slowly while stirring tempers them, so they blend in evenly instead of scrambling. Gentle heat and even mixing keep the custard smooth.
Swap the lemon
How well each one fits the dish's main ingredients (milk, sugar, egg, cream):
- Vanillafits better
- Strawberryfits better
- Raspberryfits better
- Lemonthe original
Fit is the average pairing score against milk, sugar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
