I had chicken sashimi when I first lived in Japan. I thought they were joking and seeing how far they could get the dumb gaijin to do stupid things.
It was nothing to write home about. Once in a lifetime is enough.
The advantage of having a terrible cook for a mother is that I’ve eaten enough tasteless food that if my relatives were to cook something not up to my standards then I could manage to eat it.
It’s not like the OP is having to eat there daily.
If I’m making them on the grill, then the grill marks count as a sear. However, like hamburgers, I prefer my steaks on a flat cooking surface for maximum sear. And, yes, pink in the middle. (I actually do something called a reverse sear with steaks, where I bring them slowly up to about 115 internal and finish on a blazing hot pan or grill.)
