Traditional Custard Recipe Natillas

Grate the lemon peel and set aside.

Dissolve the cornstarch in a saucepan with half of the milk.

Separate the egg yolks from the whites and set the whites aside.

Add the yolks to the milk and whisk well.

Heat the remaining milk over medium heat in a pot, adding the sugar and the grated lemon peel.

When the milk begins to boil, add the first mixture (milk with cornstarch and yolks) and heat over low heat.

Let it simmer, stirring constantly, until the mixture thickens.

Meanwhile, beat the egg whites until stiff peaks form, adding a little sugar.

Pour the custard into cups or small bowls.
