Step 5: Incorporate the Half and Half

Picture of Incorporate the Half and Half
Microwave the half and half for 30 seconds or until it is almost boiling.

Then, slowly pour the half and half into the egg and sugar mixture while whisking vigorously.  Make sure that you do not add the half and half too fast and make sure that you whisk the mixture the entire time the half and half is being added or else you will make scrambled eggs instead of White Chocolate Mousse.
