Preheat oven to 300°F.
Season all sides of brisket with baharat.
Heat a large roasting pan, generously coated with evoo, over high heat. Sear
brisket until dark brown and crusty. Turn over and sear the other side.
Remove brisket from pan and saute onions for 10 minutes, on medium heat
until tender. Add the sliced garlic and saute an additional 2 minutes.
While onions are sauteing whisk together tomato paste, wine, orange juice
and silan in a medium bowl.
Place brisket into pan of sauteed onions, pour sauce over brisket and cover
pan tightly with foil. Braise at 300°F for 3 hours until a fork can be inserted
and removed with no resistance. Cool brisket before slicing.
Strain fat off of braising liquid. Slice brisket and drizzle braising liquid
over brisket slices before serving. Top with pistachio mint gremolata.
