First, you need the right potato. A russet potato is your best friend here—it’s starchy and dry, unlike those waxy red ones that just turn to paste. Grate them on a box grater, but don’t stop there.
Here’s where it gets wild: you have to rinse the shreds in cold water. Why? Because you’re washing away the excess starch that makes hash browns gluey. It’s like giving your potatoes a spa day—they come out cleaner and happier.
Then, and this is the non-negotiable step: wring them out like you’re strangling a dish towel. Use a clean kitchen towel or cheesecloth, and squeeze until your hands ache. No water = no steam = incredible crunch.
