Why it works: Milk and cinnamon are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 12,655 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Boiled Custard
Ingredients
Directions
Make the custard
Bring 3 pints of milk and broken cinnamon sticks to a boil in a kettle.
Beat 2 eggs (discard 2 egg whites) with sugar to taste in a bowl.
Once the milk boils, pour it into the egg mixture while stirring constantly.
Place the bowl in the kettle with boiling water.
Stir until it thickens, being careful not to curdle.
Remove the bowl and let it cool.
Assemble and serve
In a glass bowl, layer pieces of sponge cake and sprinkle with sherry wine.
Strain the custard into the bowl over the sponge cake.
Whip the reserved egg whites with currant jelly.
Before serving, spoon the whipped egg whites on top of the custard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the body of the custard as it thickens with the eggs.
- Eggs
- Thicken the custard as they set with gentle heat, giving it body.
- Sponge cake
- Soaks up the sherry and gives the dessert a soft, absorbent base.
- Sherry wine
- Adds aroma and flavor to the soaked sponge cake layer.
- Currant jelly
- Sweetens and flavors the whipped egg whites that top the custard.
The step that matters
Stir until it thickens, being careful not to curdle. Egg proteins set at gentle heat, but too much heat or stirring too little lets them clump and curdle. Constant stirring over steady, indirect heat keeps the custard smooth.
Swap the currant
How well each one fits the dish's main ingredients (milk, egg, sugar, cinnamon, sherry, wine):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against milk, egg, sugar, cinnamon, sherry, wine. Candidates are from the same food group and used in at least 100 recipes.
