What each ingredient does

Egg yolks
Add richness and help thicken the custard as they set with gentle heat.
Milk
Forms the liquid base that gives the custard its body and creaminess.
Corn starch
Thickens the milk so the custard holds its shape when turned out.

The step that matters

Adding the corn starch to the warm milk. Stirring constantly keeps the starch evenly dispersed so it does not clump, which would leave lumps in the finished custard.
