Mmmmm, steak tartare. I love that.
You can’t really order a fastfood burger rare. They’re too thin. It’s cooked or not cooked.
I agree about trying to order a medium-rare burger in a restaurant and letting them know if it’s been overcooked in the past. I can’t stand overcooked burgers.
At home I’ll cook them bloody rare. Yum yum. Steaks rare too. But I’m not going to put the onus on a restaurant to do it.
