We grind onion, garlic, mustard and olive oil in a blender.
The resulting mixture is spread on the washed brisket and left for 1 hour in a cold place.For the sauce, mix the tomato paste and ketchup with all the spices and honey. Mix until smooth and do not forget to add salt.We release the pork from the marinade, wrap it in foil and send it to the oven for 1.5-2 hours, at a temperature of 180 degrees.
After this time, we take out the brisket and open the foil. Here, to get a crispy crust, you can return the meat to the oven for 15 minutes, without foil, but I forgot to do it)).
Spread the meat with our sauce and return to the oven for another 15 minutes, at the same temperature.You can serve it with any side dish, but since the dish is very greasy, it is better to serve it with a fresh salad )
