I was at a restaurant tonight, I ordered a sirloin, rare, and when it arrived it was purple inside & not very juicy.

I have noticed this on occasion before.

Normally it is pink towards the outside & then gets slowly redder into the middle and is quite bloody in the centre. When it looks like this is is usually really juicy & leaves quite a bit of bloody juice on the plate.

However sometimes it is more of a dark purple than red, and these ones tend to be less juicy & less bloody, and the texture isn't quite as nice.

ANyone know what the fuck is going on here?
