Deli Brisket

1 (4 pound) beef brisket
1 large onion, thinly sliced
1 tablespoon garlic powder
1/4 cup ketchup
1 tablespoon all-purpose flour

Place brisket fat side up in crock pot. Sprinkle garlic powder on top and rub ketchup generously into brisket. Add onion slices all around and on top of meat. Add enough water to coat the bottom of the crock pot. Cook on LOW, all day, for the most tender brisket you will ever eat.

For gravy, remove brisket and turn thermostat to HIGH. Mix flour with 1/4 cup water, add to pot and bring to a boil, stirring constantly.
