Custard - cooking recipe

Ingredients

1 1/2 cups milk
2 teaspoons cornstarch
1 tablespoon sugar
3 egg yolks
1/2 teaspoon vanilla extract

Preparation

Mix 2 tablespoons of the milk with the cornstarch in a heavy-bottomed saucepan.
When the cornstarch is dissolved, slowly add the rest of the milk and sugar, and cook over moderate heat until the sauce starts to thicken and comes to a boil.
Remove from heat.
In a small bowl, beat egg yolks with a fork.
Take a cup of the sauce, and slowly add to the eggs, beating briskly as you pour.
Return the egg/sauce mixture to the saucepan, stirring into the hot sauce.
Bring back to a boil, stirring constantly.
Remove from heat, and add the vanilla extract.
Pour custard into a jug or pitcher, and serve.
Tip: To prevent custard forming a skin as it cools, cover jug with plastic wrap.
