Why it works: Milk and corn are a kitchen classic. They rank in the top 10% of all ingredient pairs, and 6,955 recipes mention both. Both carry hexanal, which smells green, grassy. The science ↓

Ingredients
Directions
Prepare
Separate the egg yolks and whites in a cool room.
Beat the whites until stiff.
Make the custard
Heat the milk in a double boiler until it rises.
Stir in the corn starch and heat again.
Whip the sugar into the beaten yolks.
Gradually add the hot milk, stirring to prevent curdling.
Return the mixture to the heat and stir constantly until it thickens.
Remove from heat.
Finish and serve
Fold in the whipped egg whites and pour into cups.
If desired, add lemon juice or fruit jellies on top.

Sugar and lemon share little aroma chemistry, yet 53,532 recipes mention both: they likely 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
- Yolks thicken the custard and whites, whipped, lighten its texture when folded in.
- Milk
- Forms the liquid base of the custard, which sets as it thickens.
- Corn starch
- Thickens the milk on heating so the custard becomes firm and smooth.
- Sugar
- Sweetens the custard and adds to its body when whipped into the yolks.
The step that matters
Adding the hot milk to the yolks. Pouring hot milk into yolks too quickly can scramble them. Adding it gradually while stirring tempers the yolks so the custard thickens smoothly instead of curdling.
Flavor stand-ins for the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (egg, milk, corn, sugar):
- Vanillabetter flavor fit
- Coconutbetter flavor fit
- Figbetter flavor fit
- Lemonthe original
Fit is the average pairing score against egg, milk, corn, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“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.
