The secret to crispy hash browns — as we’ve shown you before — is getting as much water out of the potatoes as possible. You can avoid the mess from squeezing them out by using a salad spinner.
Potatoes are full of water, so after you peel and grate them, you need to express that water to get the crispiest hash browns. Typically this is done by wrapping up the shredded potatoes in cheesecloth and giving them a few good squeezes. This method can be messy and a bit time consuming, though, and requires a bit of hand strength.
Thankfully, you can give them a few good spins in a salad spinner to do just as good a job. You can even go ahead and salt and pepper them before spinning to get a good, even coating.
