You might be tempted to use a mandoline slicer for perfect, professional thickness. I get it—it’s shiny and clicks like a robot toy. But here’s the hard truth: mandolines are the crabby uncles of the kitchen. They will slice your fingers faster than you can say “I should have paid attention.”
For the love of all that is holy, use the hand guard. And if you don’t have one, just use a knife. A sharp chef’s knife is safer, quieter, and won’t make you feel like you’re operating a guillotine for vegetables. You are not a contestant on a cooking show; you’re just trying to feed your family without an ER visit.
