Heat 1 1/2 inches vegetable oil in a pot over medium-high heat until it reaches 375 degrees F. Cut a pineapple into chunks. Toss with 1 cup milk, then drain. Dredge in sugar, then fry until golden, about 1 1/2 minutes. Transfer to a rack and immediately sprinkle with more sugar, then roll in unsweetened shredded coconut.
TIP: For a fun presentation, thread fried pineapple chunks on wooden skewers, then stand the skewers upright in a pineapple base.
