This gadget cores and slices a pinapple simply and effectively. You just cut off the top of the fruit, center the tool on the top, and apply pressure in a twisting motion. As the tool screws down through the pineapple it cuts the fruit into a spiral with no peel or core. The only problem I have is that an outer margin of fruit does go to waste, but considering the time saved it’s worth it. You also have to take care to center the tool to begin with.
I paid less that $10.00 for this plastic version right at the grocery store. If you eat a lot of pineapple, it might be worth paying more online for a stainless steel model.
