Let’s get thrifty. Grab a fork and a paring knife. Hold the fork with the tines pointing up, and rest the potato on the prongs. Now, carefully run your knife down the fork’s tines—like you’re scraping butter off a cob of corn.
This makes raised ridges in the potato that separate into little shreds. It’s messy, it’s scrappy, and it feels like rebellion. Perfect for when you’re angry at the grater and want to show it who’s boss. Just watch your fingers; the fork isn’t a cage guard.
