How long after peeling potatoes should you cook them?

Here's why:

* Starch: Potatoes start to release starch as soon as they're peeled, which can make them gummy or sticky when cooked.

* Oxidation: Exposure to air causes the potatoes to oxidize, turning them brown and making them taste less pleasant.

* Moisture Loss: Peeled potatoes lose moisture more quickly, making them dry out and potentially less flavorful.

General guidelines:

* Immediate: For the best texture and flavor, aim to cook them within 30 minutes of peeling.

* Up to an hour: You can store peeled potatoes in cold water for up to an hour. This helps to slow down the starch release and oxidation process.

* Longer storage: If you need to store them for longer, submerge them in cold water with a tablespoon of lemon juice or white vinegar. This will help to prevent browning.

Ultimately, the longer you wait, the less desirable your potatoes will be.
