I recently bought an eighth of a 'Coo'. This fine animal was reared in Cunningsburgh by Hazel and Kenneth MacKenzie. He was a Saler/Simmental Cross and his name was Chooka Parker. He was slow reared and slaughtered at the Lerwick Abattoir at 30 months (any older and regulations dictate that the carcass must be split and the spinal cord removed).
He was then hung for three weeks.
The biggest of the cuts I bought was a hefty piece of rolled brisket weighing just over 4 kilos. The brisket is cut from the chest muscle of the animal which bears more than half of its weight, consequently the meat can be tough - so it is ideal for long, slow, moist cooking.
I had a big family gathering coming up so this provided an ideal main course.
Spiced beef is a very traditional dish in Ireland around Christmas and I carried out a bit of research to find a good combination of seasonings (Elizabeth David - 'Spices, Salt and Aromatics in the English Kitchen' and Theodora Fitzgibbon - 'A Taste of Ireland in Food and Pictures').
Traditionally, saltpetre (potassium nitrate) is used to produce the characteristic pink colour of cured meats. It is not easy to find in the small quantity needed : a piece of bacon added during cooking will help provide this effect. However, I did not use it at all and and adjusted the salt to take account of this, I was also very happy with the finished colour.
Forward planning is essential.
