resurrecting an older thread...but i had some folks over for dinner on St. Patty's day for a brisket and it went a little like this:
rub brisket with 1/2c brown sugar, and place in baking dish that has a cover. quarter one onion, and slice 3 cloves garlic, add to dish, and pour in 2 cans of Guinness Stout or Oatmeal Porter, along with a can or two of water (just to cover the brisket, which by the way is fat side down to start) and chuck in about 10 peppercorns.
Chuck it in the oven, 300 degrees, 4 hours.
take out, flip to fat side up and put back into oven uncovered.
While it was cooking, you prepared your veggies - B-size red taters (half or quarters), large carrots (not them dang baby carrot obamanations) cut into 1-2" chunks...use the fat carrots, and cut your cabbage head into 8'ths leaving the core intact on each wedge.
at the point you flipped the brisket (which should be dang near fall apart tender already), start cooking the veggies.
In a large pot, put a few tablespoons of bacon grease (doesn't everyone keep a jar of this nectar in the fridge?), and brown the sides of the cabbage...yes...fry the cabbage till it's got some color. doing the cabbage in batches until finished, just browning them and pulling them out. once you are done with it, toss the taters(halved or quartered) and carrots (1.5 to 2" chunks) into the pot, cover with the cabbage wedges, and add about 2 cups of the liquid from the brisket. cover, and let cook over medium heat for about 20 mins or so until carrots and taters are done. the cabbage won't be soupy mess, the taters will look like taters, not brown boiled oats, and the carrots will be ORANGE...not brown
I took more of the braising liquid, and the liquid from the veggies, strained it through a papertowel and made a gravy out of it with ample pepper, a little salt to taste and hit it with the old corn starch trick.
my family, my guests, and myself have elected me to be the purveyor of all StP's corned beef meals forevermore. it was a HUGE hit, the best they've ever had and they LOVED the different treatment of the veggies. give it a try, you will love it too, i'm certain of it.
Serve with a good hearty artisan bread...something with a good crust and lots of holes...cus once the CB is gone, folks started eating gravy sandwiches LOL...my mouth is watering...i need to go now...
