I generally dislike one-use kitchen products. I think it stems from never having had the luxury of a spacious kitchen, but also my neurotic need to have things absolutely, 100% clutter free. My belief is that unless I can't make a recipe without it, or it's usefulness far outweighs the burden it puts on my precious kitchen space, it's trash. Some examples: Apple corer? Trash. Avocado slicer? Trash. Ice cream maker? Can't do without it.
