Why it works: Sugar and gelatin are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,778 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Creams and Custards
Ingredients
Directions
Prepare
Beat the eggs quickly and sharply, separating the whites and yolks.
If using gelatin, soak it in cold water or milk for 1 hour.
Dissolve the gelatin in a warm place.
Make the custard
In a custard kettle, heat the milk until it begins to foam.
Add the sugar to the boiling milk to cool it slightly.
Mix the beaten yolks with the sugar in a bowl.
Gradually add several spoons of the hot milk to the yolk mixture.
Slowly stir the yolk mixture back into the boiling milk, stirring constantly until it thickens slightly.
Remove from heat immediately to prevent curdling.
Cool the custard in a cold dish.

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 as they set with gentle heat, giving it body.
- Milk
- Forms the liquid base of the custard, providing moisture and creaminess.
- Sugar
- Adds sweetness and helps cool the hot milk before the yolks are added.
- Gelatin
- Adds firmness by setting the custard as it cools.
The step that matters
Remove from heat immediately to prevent curdling. Egg yolks begin to set around 160°F and scramble if overheated. Stirring constantly and removing the custard from heat as soon as it thickens keeps it smooth.
