It’s super simple to keep those potatoes from browning after they’ve been peeled.
Just put them in a bowl with cold water and you can add some lemon juice or a bit of vinegar. This helps to keep the potatoes from oxidizing because they’re not exposed to the air.
Regardless if you’re keeping them whole or cutting them up, let them sit in the bowl while you handle other things. Be sure not to let them soak for too long though so they don’t lose nutrients. Try to keep it within 2 hours.
