Best on well done, because it moistens the overly dry meat.
I say this as a lover of A1, and lover of medium steaks.
I grew up with leather and A1, and I still like that from time to time. Now I’ve come to love medium steaks, and if seasoned and cooked correctly, I don’t need A1. Though I still crave it, and will use it on my own steaks at home.
It’s not often I usually prefer medium rare and then I’ll only use it to dip in, but not all the time.
But it’s actually best on well done

All in all, steak is delicious.
