Do not ask me how I know,
As stated above get some very fresh "Elephant Ear" Tabs,( that what the leaf is called in the horticulture community). Best place if U close to Dallas is the Arboretum, they have a section just for cooking aficionados. I think the Tabs are sold by the ounce. If you can Brine the entire pachyderm for 60 - 72 hours it will be very tender and tasty. Then place on grill best size is 120 in X 144 in. coals about 36 -72 inches below meat. use one those re-mote sensors for temp, actually you will need about 10 of the units to place around for even temp readings. I gotta get back to work for awhile, then I will complete my instructions.
