Apricot Glazed Flanken

1 Preheat the oven to 325 F
2 Slice the onions and chop the carrots, then add them to a dutch oven or braiser.
3 Add the meat pieces on top, and drizzle with the olive oil. 
4 In a bowl, whisk together the apricot jam, coconut aminos, mustard, salt, pepper and water. Pour the marinade over the meat and vegetables.
5 Cover the pan and bake for about 3 1/2 hours. The meat should flake easily with a fork. You can set the pan under the broiler uncovered at the end for 3 minutes to brown the edges before serving.
