Remember to remove your meat from the packaging, pat dry and bring to room temperature.
Pre heat your oven to 135°C temperature.
Next choose a suitable sized oven proof casserole with a tight-fitting lid.
Season the meat with salt and pepper or your preferred seasoning
Make a mirepoix by neatly chopping equal amounts of onion, carrot and celery, the root of the celery plus a bay leaf, sprig of rosemary and a few black peppercorns, another nice addition would be a head of garlic split in half.
Take a large, heavy based frying pan, and add a few drops macadamia oil.
Sear the Osso Bucco pieces on both sides in small batches then transfer to the casserole dish.
Next fry the mirepoix until lightly coloured.
Then add half a bottle of Leleshwa White Wine and reduce by two thirds then add 500ml of beef stock, 1 tablespoon tomato paste (optional) and reduce a little, thicken with a tablespoon corn flour mixed with a little cold water and stirred into the boiling broth.
Pour the sauce over the meat and cover. Place in the centre of the oven and cook for 3 to 4 hours, the meat should be tender when pierced with a meat fork and fall away from the bone.
Remove from oven, carefully take out the meat and keep warm. Pass off the juices through a fine sieve into a clean saucepan and reduce to a glossy finish then pour back over the meat ready to serve.
