Place Brisket And Water In Dutch Oven; Cover Tightly And Cook 1 Hour At 350 Degrees (F). ( It Is Very Important To Simmer The Meat Slowly Because Boiling Will Cause Meat To Become Tough.) Turn Brisket Over And Continue Cooking, Covered, 1 1/2 To 2 Hours, Or Until Meat Is Tender. Remove Brisket From Cooking Liquid And Place, Flat-Side Up, On Rack In Broiler Pan So Surface Of Meat Is 3 To 4 Inches From Heat. Combine Honey With 1 Tablespoon Mustard; Brush Half Of Mixture Over Top Of Brisket And Broil 3 Minutes. Brush With Remaining Mixture And Continue Broiling 2 Minutes, Or Until Brisket Is Glazed. Meanwhile, Steam Cabbage 15 To 20 Minutes, Or Until Tender. Combine Remaining Mustard With Butter And Dill; Spread Over Hot Cabbage Wedges. Carve Brisket Diagonally Across The Grain Into Thin Slices And Serve With Cabbage.
