My wife and I have been married for 10 years as of this Friday. In the early years, she would not eat that much beef. I like steak rare and she just did not care for it that much. In the last 4-5 years, she has developed more of a taste for steak and prefers it med-rare. But it HAS to be a good cut. I agree with her on that but I lke it a bit more rare. Kids? Daughter likes it more done, son does not care. He just eats what we give him.
So, Dave, your line of reasoning holds a similare line here.
Oh, BTW, when I cook ANY meat, be it mammal or fish, I will always cook it to the level of desired doneness (sp?) and when I pull it from the grill, I immediately cover it with foil for about 3-4 minutes. (Just enough time to prepare the rest of the plate.) Heat is still escaping and taking moisture with it. While covered, the moisture has no place to go and the meat stays moist. Little trick works pretty good. Try it!
