Very rare with crispy fat.
Unfortunately, DP believes that tough enough to keep the dentist busy is exactly the same as very rare and on the one occasion I'd insisted on cooking my own (and promptly got dizzy, which is why he cooks) and had a perfect steak resting, in the time it took him to manage to boil some potatoes, I realised that the beeping wasn't for extra veg, it was him microwaving it FIVE TIMES.
So I don't buy it anymore.
