I really really like my eggs sunny-side up and so does my husband. But I can never get my eggs to cook quite right- where the white is cooked all the way through without the yolk being cooked too. I have success when I cook it about halfway, then flip it and cook it for a couple seconds to finish the whites off. The yolk is nice and runny that way, but then my eggs just don't look very good, and I like pretty eggs. Silly, ain't I? Any tips?
