Medium rare, on the rarer side. But cooked in a pan so hot that the outside is blackened.
I'd usually go for fillet though and have that rare to blue, but the outside still needs to be burnt (so far as possible).
H has to cook his steak separately to me as the weirdo likes the same level of rareness as me on the inside but with the outside barely cooked either?! That to me is what adds the flavour! His steak looks like old grey leather (he has his bacon the same 🤢).
