Lulu, just like riding a bike, you have to get on in order to get it right!
We also like ours really rare, and you will, in any case, get more of the "crust" on it if you get your pan VERY
hot before you put the meat in.
I just rub it with salt and pepper, and sear it on both sides, then slide the pan into a heated 400 degree F oven for about 3 minutes.
