5: Pour the hot milk onto the egg yolks + sugar and mix well.
6: Wash the pan, and pour the mixture back into it through a fine strainer to eliminate any small impurities which are left.
7: Put on medium heat, and cook while stirring continuously, scraping the bottom of the pan with a maryse or a spatula. To start with you will notice that the mixture doesn't "glaze" the maryse or the spatula.
8: But when custard is cooked, it "glazes" the spatula. This happens after about 10 minutes. Be careful during cooking: the custard should never boil, otherwise it will go lumpy... If unfortunately this happens to you, take off the heat immediately and mixer for a few seconds.
9: Other way to be sure of good texture, use a thermometer and stop cooking at 180-185°F (82-85°C), never more.
10: When ready, take off the heat and plunge the bottom into a little cold water (in the sink will do fine) to stop cooking, leave to cool, stirring from time to time.
11: When cold, your crème anglaise is ready.
Remarks
Your crème anglaise will be better if you use full-cream milk. If you have too many egg whites, you can make meringues or financiers with them.
