Cut dough into 6 parts and roll into small balls. Then cover and let rest for 10 more minutes. Roll each dough into an 18-inch rope and twist into a pretzel. Let the pretzels poof for 45 minutes in a warm area, uncovered.
Let the pretzels rest in refrigerator uncovered for at least 2 hours, or overnight.
