I love gadgets and tools but I’m especially wary of kitchen gadgets with a single function, such as apple corers, ginger peelers, even citrus reamers (though I use enough of the latter that I actually have one!). They usually take up more space than they’re worth. Enter this pineapple slicer. I was very skeptical. I thought it would waste a lot of the pineapple, or do an unsatisfactory job, but I was actually surprised.
