And my favorite part: You can use your leftover pineapple for all kinds of sweet treats. Make a batch of candy corn-inspired pineapple-orange parfaits or mix up a pitcher of our mulled cider and pineapple cocktail. No matter how you carve them, these pineapple jack-o’-lanterns will make a big statement—we’ll show you how to carve a pineapple in three easy steps in less than 30 minutes! To keep your carved pineapple fresh, store it in the refrigerator when not displaying.
