Lamb shanks are a frequently overlooked cut from the sheep - there's lots of cartilage and tendons and collagen in them. So they need a good long cook, either in the oven, or in a slow cooker/crockpot, or sous vide. In this recipe, I also show you how to make a simple but delicious red wine reduction sauce.

2 lamb shankss
1 medium onion
1 carrot
1 stick celery
1 sprig rosemary
SAUCE
200 ml lamb stock
200 ml red wine
a knob of unsalted butter
2 tsp flour1 tbsp olive or rapeseed oil if cooking sous vide
