Braised lamb shank

We wanted to try some wild boar this weekend, as it is the season, but our regular butcher at the market, M. Stoltz, was not there. Fortunately, we have a very good butcher just around the corner from us, and we walked in there to get our marcassin. Unfortunately, they did not have any, but they did have souris d'agneau, which seems to translate as lamb shank or knuckle. I called a shank, found a recipe, and made what I think is a very good meal of braised lamb shank. You can serve it with mash. The quantities here are for 2 shanks or people, depending on how hungry you are, but it's all scalable:

2 lamb shanks (about 700g), room temperature
2 onions, diced
3–4 medium carrots or 2 big ones, chopped up into chunks
4 cloves of garlic or to taste, minced
250 ml dry red wine
200 ml chicken stock
200 ml beef stock (I made mine using Bovril, but you do you)
400 g tin diced tomatoes
Rosemary, sage, bay leaf to taste (I used a bouquet of herbs that my wife had bought earlier. You can mix and match to your taste, though)
Lemon peel/zest to taste (about half a lemon's worth should do the trick)

Season the shanks on all sides. In a big Dutch oven or large pot, heat some oil and brown the shanks on all sides, which should take about 6-10 minutes. Once that's done, put the shanks to one side and add the onion, carrots, and garlic, and cook until soft, about 5 minutes. When ready, add in the rest of the ingredients (be careful with the liquid ingredients: don't pour it in all at once. Keep some to one side just in case. You don't want to overdo it) and then return the shanks to the liquid. Make sure the liquid covers the shanks, bring to the boil, cover, then simmer over a low heat for 1.5–2 hours. When the meat is tender, uncover and leave to simmer for another 15–30 minutes. Once done, remove the shanks, wrap them in foil and put them in the oven. Turn the heat up and boil the sauce for another 15 minutes or so to reduce.

Serve the meat and sauce over mash, and don't ditch the bones until someone's gnawed on them.
