Piglet, you CAN do this - just season the brisket, dump it into the bag & enjoy the fragrance that will permeate the house once it gets going!
BTW, I know it sounds like a lot, but I use the whole bottle of liquid smoke. Even if I have time to marinate, I typically leave it in the roasting bag while cooking. If I'm using the brisket for chopped BBQ Beef, I'll save the liquid / au jus and add it to my crock pot with the BBQ sauce to keep the beef moist & flavorful.
shovan & Kathy - Now you've got me going in search of those jerk pork recipes. Food on a stick =

from the kiddos!
cajunmommy, You have me craving brisket now!
Here's the Emeril recipe I did. Along with the changes I made to the sauce. I sort of combined the two sauces, but using what I had in the house & my own quirky additions. But I hardly changed anything in the marinade & it really rocked! It really got into the pork & had an authentic jerk flavor to it. Nice & spicy too! Just like us cajuns like it! It would be really good cutting the pork into cubes & doing cabobs. The best part was the charred crust that formed on the pork loin. (I started marinating it at about 8:00 am)
Jamaican Jerk Pork Tenderloins with Gingered BBQ Drizzle Recipe courtesy Emeril Lagasse, 2006
2 (1 to 1 1/2-pound) pork tenderloins, trimmed of fat
1/2 cup fresh lime juice
1 cup Jerk Marinade, recipe follows
2 teaspoons kosher salt
Vegetable oil
Gingered BBQ Drizzle, for serving, recipe follows
Rinse meat well and pat dry with paper towels. Rub the lime juice all over the meat, place in a nonreactive bowl, and set aside, refrigerated, for 15 minutes. Add the Jerk Marinade and turn to coat meat well. Cover with plastic wrap and refrigerate for at least 4 hours or up to overnight.
Preheat a grill to medium-low. Remove the meat from the marinade, leaving some of the marinade clinging to the surface of the meat. Season the meat with the kosher salt and lightly oil the grill grates. Place the tenderloins on the grill and cook, turning occasionally, until the pork is just cooked through and nicely browned on the outside and a thermometer inserted into the center registers 145 to 150 degrees F, 28 to 30 minutes. Remove the tenderloins from the grill and allow to rest for at least 10 minutes before serving. When ready to serve, slice the tenderloins into 1/2-inch thick slices on a slight diagonal and serve fanned out on a plate, drizzled with the Gingered BBQ Drizzle.
Fried plantains and/or any sweet potato dish would both make nice accompaniments to the pork.
