*If you're worried about raw eggs, you can do what I did. Place the egg yolk bowl over a pot of water on medium-high heat. As the water bubbles lightly, whip the egg yolks constantly until they are warm and slightly cooked (but not scrambled -- that's why you need to whip constantly!). This kills any possible bacteria. Plunge the bowl into a sink with a couple of inches of cold water and keep whipping to rapidly cool the eggs. You can skip this step if you want.
