I fire up my old gas grill, crank it to 550, throw the generously salted and peppered 6 or 7 lb. Butt on and sear it for about 10 minutes total... I get it nice and grill-marked on all sides. Crispy is good! Then I throw into a tight fitting, covered, oven pan, those oval shaped dark blue w/white speckled ones! I turn the grill down so the temp is right at 200... no higher!!! I add a chopped onion, a few teaspoons of chopped garlic and a medium (14oz) can of diced or crushed tomatoes and let it slow cook for at least 6 hours, 8 or 9 is perfect. Amazing, awesome flavor and super tender... it never fails! Serve on rice or with tortillas, beans, etc.
