Rubbing the beef with flavourful spices before cooking it to tenderness makes this roast a winner. For an informal family event, slice thinly and serve on kaiser rolls. If you can't find strained tomatoes, just process 1 can (28 oz/796 mL) whole tomatoes in the blender until smooth and strain out seeds.

3 tbsp (45 mL) paprika
1 tbsp (15 mL) kosher salt
1 tbsp (15 mL) black pepper

1 tbsp (15 mL) ancho chili powder, (or chili powder plus 1/4 tsp/1 mL cayenne)

1 bottle (341 mL)beer
In large bowl, combine paprika, salt, pepper, sugar, chili powder and garlic powder; stir in oil to make paste.
Add beef brisket, turning and rubbing in paste well. Cover and let stand for 1 hour. (Make-ahead: Refrigerate for up to 24 hours.)
Place brisket, fat side up, in greased roasting pan; roast in 400°F (200°C) oven for 30 minutes.
Barbecue Sauce:
In blender, mince chopped onion with garlic. Add strained tomatoes, brown sugar, cider vinegar and Worcestershire sauce; whirl until no large chunks remain. Stir in beer. Pour over brisket.
