Here’s how to keep potatoes from turning brown, so they’ll be worthy of both your finest dinner party and your casual weeknight meals. (Thesepotato salads are perfect for either!)

Why Do Potatoes Turn Brown?

If you’ve ever cubed a potato only to come back to a brownish-gray mess on your cutting board 10 minutes later, you’re not alone. Potatoes brown quickly when exposed to fresh air because they are jam-packed with starch. When this starch is exposed to oxygen, they undergo a process called oxidation, which leaves your potato with a grayish or brownish tint. They’re 100% edible, but instantly less appetizing.

The easiest (and most common) method for protecting your precious potatoes from browning is to use cold water. When sliced potatoes are placed in water, the oxidation process slows way down.

Grated potatoes (like the ones you need for these creamy hash browns) brown even faster than cubed ones, so waste no time getting them into water. Fill a bowl with just enough cool water to cover your potatoes by about an inch. Place your mandoline and grater directly over the bowl and cut straight into the water to keep your potatoes as white as possible.

Editor’s Tip: Sliced, shredded, cubed or really any kind of peeled potato can be stored in cold water for about 24 hours before any noticeable change happens to the potato’s structure or texture.

Add lemon juice or vinegar

Placing spuds in water will slow the oxidation process, but it will not stop it. To keep keep potatoes from turning brown for more than six hours, say overnight, then add a bit of acid.

Lowering the pH of the potato helps fight off oxidation. Just like you might use a squirt of lime juice to keep guacamole from browning, a bit of lemon juice or white vinegar in the bowl with the potatoes will ward off gray hues. Use one teaspoon to a half gallon of water to get all the anti-browning impact with no noticeable flavor changes. Learn how to wash potatoes in the right manner.
