Yesterday, I tried to use our new BGE and the BBQ Beef Brisket recipe, cookbook p. 40, to have a 4.47 lb. brisket ready for dinner about 7:30 p.m. After doing everything per the recipe, making ajustments for the greater weight of my brisket, I put it on the BGE at 5:30 p.m. I will say that in my more than 35 years of grilling experience, I have never seen a grill I could so easily ajust to hold a precise temperture as the BGE. Yet, at 9:30 p.m. I gave up. It still wasn't done. My wife put it in the oven and cooked it for 2 more hours @ 300 deg. We're having it tonight and she says it's delicious. However she also says she cooks a brisket all day. What did I do wrong - what happened?
