Putting 2 13# briskets in at midnight for a New Years Eve party. Planning on 15 hours at 235. They have been in the fridge all day with the normal beef rub. Equal parts onion and garlic powder, pabrika, black pepper, and kosher salt. Plan to put the temp probe in the bottom brisket and check both when it hits 195IT. All three briskets I have done in this smoker have been great so far but have never done 2 at once. Hope all goes well. Will let you know how it goes. Pictures soon to come. Will be using a water pan 3/4 full. Hope that is enough.
