I've been cooking for myself for some years now and I don't have an electric thawing machine - microwave. I'm always forgetting to take the meat out of the freezer before I go to work. No problems, I just cook it frozen, either in a frying pan or in the oven. Pork, lamb, beef, chook ( chicken ), turkey, fish, koala bear etc. The only proviso is, as mentioned by others, is to make sure the product is properly cooked.
It all tastes great to me.
