If baking 2 cookie sheets at one time, switch positions halfway through baking.
Pistachio nuts are easy to shell because the shells open naturally when the nuts are ripe. Discard unopened pistachio nuts; they are not ripe.
Shelled pistachio nuts are more expensive, but they save prep time. Look for them in the grocery store produce department near the bulk nuts and dried fruit.
To transfer the dough round to the cookie sheets for baking, use two large pancake turners.
