how far in advance can you peel potatoes

It’s generally not recommended to peel potatoes too far in advance, as this can cause them to turn brown or gray due to oxidation. This is because potatoes contain an enzyme called polyphenol oxidase, which reacts with oxygen in the air to produce a pigment that causes the potato to discolor.

That being said, if you need to peel potatoes ahead of time, here are some guidelines:

* If you’re using the peeled potatoes within a few hours, you can peel them and store them in cold water to prevent discoloration. The water should be changed every 30 minutes to an hour to keep the potatoes fresh.
* If you’re using the peeled potatoes within 24 hours, you can peel them and store them in a sealed container or plastic bag in the refrigerator. Make sure to press out as much air as possible from the container or bag to prevent oxidation.
* It’s not recommended to peel potatoes more than 24 hours in advance, as they can become soggy and develop off-flavors.

To minimize discoloration, you can also try the following:

* Use a acidic ingredient like lemon juice or vinegar to help prevent oxidation.
* Use a product like Fruit Fresh or Browning Inhibitor to prevent discoloration.
* Peel the potatoes under cold running water to minimize exposure to oxygen.
* Use a sharp peeler to minimize damage to the potato cells, which can contribute to discoloration.

It’s worth noting that some potato varieties are more prone to discoloration than others. If you’re looking to peel potatoes ahead of time, it’s best to use a variety that’s known for its resistance to discoloration, such as Russet or Idaho potatoes.
