How to Keep Grated Potatoes From Turning Brown Before I Use Them

Updated February 21, 2017

Grated potatoes are a luscious base for many comfort foods, including potato pancakes and hash browns. Such recipes are often made by mixing the potatoes with a few other ingredients and pan frying them. Potatoes should be cooked quickly after they are peeled in order to prevent the flesh of the potatoes from browning. However, a simple series of tricks can keep your vegetable looking fresh even if it's been prepared ahead of time.

Add lemon juice or vinegar to a bowl of cold water.

Peel your potatoes. Place the peeled potatoes into the cold water bath until you are ready to grate them. The water bath will prevent the grated potatoes from browning too quickly.

Grate your potatoes. Do not store the grated potatoes in cold water. The water will cause the starch to leak out of grated potatoes and prevent them from sticking together when cooking. Instead, mix the grated potatoes with a chopped onion and keep the mix in the fridge until ready to use. The onions will be a great addition to the flavour of your recipe and will prevent the potatoes from browning.
