Consequently, Iâm often asked how to use different-size eggs. Even though large eggs are the accepted standard in American recipes, you may find that your supermarket has extra-large eggs on sale one week and then jumbo eggs on sale next week.
Many variables affect cooking time and temperature such as how many times the smoker is opened, how close the brisket is to the fire box, the type of smoker you are using, the weight and thickness of the brisket, etc. Sticking to 225 degrees and 1 hour and 15 minutes puts you in the ballpark for a well cooked brisket.
A brisket should rest at least 30 minutes and up to 2 to 4 hours in a warm ice chest. Using the 1 to 1.5 hour rule and your brisket is around 12 pounds, a cooking time of between 12 and 18 hours depending on the above mentioned factors. brisket should rest at least 30 minutes and up to 2 to 4 hours in a warm ice chest.
