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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
In a saucepan, combine the eggs, powdered sugar, and lemon-flavored cream.
Heat the mixture in a double boiler, stirring until it thickens.
Remove from heat and let it cool.
Assemble and bake
Line a baking dish with the cream paste.
Pour the pudding mixture into the lined dish and add strips of citron if using.
Bake in a preheated oven at 350 °F (175 °C) for nearly 1 hour, covering the rim if it starts to burn.

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 coagulate with heat, giving the pudding its structure.
- Powdered sugar
- Sweetens the custard and dissolves smoothly into the eggs and cream.
- Rich cream
- Adds moisture and richness, giving the pudding a tender, silky texture.
The step that matters
Thickening the custard over a double boiler. Eggs thicken gently at around 160 to 180 °F; direct heat can scramble them. Stirring over moderate, indirect heat keeps the custard smooth and prevents curdling.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, cream):
- Vanillafits better
- Raisinfits better
- Strawberryfits about as well
- Lemonthe original
Fit is the average pairing score against egg, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
