Lamb Shank
Why would anyone now buy a lamb shank. Lamb shanks have become more popular over the past 4 years due to supermarkets making them more available, why? Most folk know what a lamb shank is, but maybe in this fast food, quick fix world some my not. So take your own leg as a guide, chop the foot off below the ankle, measure about 8 inches up the leg and chop off, you will hit a nice lump of meat, that's your lamb shank.
Now the supermarkets over the last 12 months have started to cut these lamb shanks shorter and shorter, hence what you have now is 75% bone, the other 25% is now just gristle, tendon and tough fibrous tissue, all for the grand total £12 per kilo. Some supermarkets and frozen food stores sell them in pretty boxes, and yes with some fab art work on the box of this big mouth watering roast, ( don't be fooled) buy 2 boneless leg chops at the same price per kilo. much better value. What they are selling you is a expensive bone.
