Lamb shanks in orange sauce

I have woken up after night duty to find the house smells like you could just eat the air. I'm suddenly starving. Matthew has started cooking tonight's dinner already. Lamb shanks in orange sauce mmmmm. Here is the recipe for the interested:

Lamb Shanks in Orange Sauce
Ingredients:
1 tabsp oil
6 frenched lamb shanks (we're not having that many seeing as it's just the two of us)
1 large onion, finely chopped
2 cloves garlic, finely chopped
strips of zest from 1 orange
250ml orange juice (we had oranges so we have freshly juiced orange juice)
375 mL beef stock (we made beef stock the other day with the meat for our chilli beef - very rich, concentrated stock - yum)
425g can chopped tomatoes
2 bay leaves
1 teaspoon thyme (recipe says dried, but we have fresh thyme)
salt and pepper
mashed potato to serve on
instructions
heat oil in casserole dish or pan over a medium to high heat, brown lamb shanks, remove from pan.
Reduce heat to medium, add onions and garlic and cook for about 2 mins. Add orange zest, orange juice, stock, tomatoes, bay leaves, thyme, salt and pepper. Stir to combine. Bring slowly to the boil. Reduce to a simmer, then return shanks to the pan. Cover and cook for 2-2.5 hours until meat is tender. Alternatively, cover and place casserole dish in 180C oven and cook for 2 - 2.5 hours.
For a thicker sauce, remove shanks from the pan, bring the sauce slowly to the boil, reduce to a simmer and cook until reduced by about 1/3. Serve with mashed potato.

Honestly the sauce smells so good I just want to go into the kitchen and drink it! Matthew has made it clear such an action would be frowned upon. I really, really love food:)

Thanks to everyone for their birthday wishes, and to Rachem - Happy Birthday to you too:)
