A pineapple corer is a kitchen tool designed to remove the core from a pineapple while simultaneously slicing the fruit into rings. It typically features a sharp, spiral blade that cuts through the flesh of the pineapple as it is twisted into the fruit. This tool makes it easier to enjoy fresh pineapple without the hassle of cutting and coring manually. Using a pineapple corer is simple and efficient. To use it, you place the corer at the top of the pineapple, press down, and twist. The corer then extracts the core and leaves you with perfectly shaped pineapple rings, ready for eating or use in recipes.
