Riverford haunch of venison with a teriyaki twist

I’m going to wrap up my Riverford Organic month with the final item from the meat box, and it’s a goody. A beautiful haunch of venison, boned and rolled at a petite 650g. I had previously cooked another venison dish from the same box – see venison goulash – but this joint seemed to come from an altogether different breed. It felt so velvety smooth and did the weird thing when you press it and it doesn’t spring back (I guess that’s like edema.. which is gross).
