The associative property of addition says that when we add more than two numbers the grouping of the addends does not change the sum. In the example above, we can easily observe that: (3 + 6) + 8 = 3 + (6 + 8). 9 + 8 = 3 + 14. 1 7 = 17. Notice that the SUM is the same no matter what way you group the addends.
Cooking a pork roast on a rotisserie grill set for direct or indirect low heat will take up to four hours for an average 5-to 6-pound roast. The finished internal temperature of the roast should be 145 F, when measured from the thickest portion of the roast.
(See here for more rotisserie setup details.). 4. Cook the roast Put the spit on the rotisserie, and cook with the lid closed. Cook the pork roast until it reaches 185*F to 190*F in the thickest part of the meat. This should take 1 to 1.5 hours; assume about 25 minutes per pound of meat.5.. Prepare and rest the roast: One hour before cooking, mix the rub ingredients in a small bowl. Remove the pork from the brine, and pat dry with paper towels. Sprinkle the rub evenly over the entire roast, working it into any nooks, crannies and seams you can find.
