what's a good technique for pasteurizing eggs?

Question

I tried to make homemade eggnog last Christmas. It turned out fine, but the eggs were an issue. I thought about buying pasteurized eggs but they would've run me $12 for two dozen, which seemed obscene.

Pasteurization was important because my young child might have wanted some eggnog, so it needed to be very safe.

So I pasteurized the eggs by heating them a little at a time in the microwave, stirring, heating etc until they reached 145F. I may have separated the yolks, but can't remember exactly. I read about the technique on a blog. This worked well enough, but I ended up with some chunks of cooked egg in the egg nog. Not a big deal, but I spent a lot of time on this eggnog and was disappointed that it was less than perfect.

What's a good technique for pasteurizing eggs that doesn't result in chunks and gets the eggs to the correct temperature?

Answer

The microwave is too harsh an environment for this.

Pasteurize them in the shell, in a large pot of water on the stove. You must bring the water up to 140 - 150 F (60 - 65 C) for 3 to 5 minutes to pasteurize them. You must not exceed 150 or you will begin to cook the egg. If the eggs are in the water as you heat it then they will closely match the temperature of the surrounding water. Just make sure they aren't resting on the bottom of the pan. If you want to be extra careful you can leave them in longer, as long as you don't let them get too hot.

Alternatively, you can combine the eggs with the milk and heat this slowly on the stove until it reaches a temperature or 140-150 F, maintaining for 3-5 minutes.

Update

You can also pasteurize in-shell at 135 F (57 C) for for 75 minutes according to this reference: http://amath.colorado.edu/~baldwind/sous-vide.html
