Ricg. WOW, can't believe someone actually believes i have an EXPERT opinion
20 hours should do it. Funny think with briskets, is they all finish differently. I cooked an 18 pounder that was done in 12 hours one time and had 12 pounders go 18. All depends on marbeling within the meat. Remember, fat side down to keep the fatshield between the heat and the meat. I also start at 180 for the first 4-6 hours, as I use a FEC 100 and it puts out more smoke at the lower temps. I flip mine over for the last couple of hours to let it self-baste. With your small 025 electric, it is probally going to retain much more moisture than my FEC and will likely get finished faster. If you get pressed against the time, you can always turn up the heat a little toward the end, not a bad Idea anyway to 'bark' it up a little. Good Luck. I'm smoking a 13.7LBer tonight. I'll put it in at 4PM, smoke for six hours at 180 and boost to 225 until internal 190. I plan to pull and cooler it around 8am before church and it will hold until lunchtime (probally about 1PM) when it is sliced).
