Preserve cut potatoes I am going to cut some potatoes tonight for a dish I am going to make tomorrow. Will keeping the cut pieces in water immediately after cutting preserve them? There are suggestions at other websites that say adding some lime juice to the water will help. Has anyone had experience preserving potatoes?
It's pretty normal in many cultures to prepare vegetables for the evening meal in the morning, or even the day before. This has a long recorded history, at least to Roman times

Typically, vegetables that brown badly in that 24 hour period are either stored under water, or coated with a suitable dilute acidic solution (orange, lemon, or lime juice)

Cut potatoes stored underwater do not seem to suffer any detrimental effect over a 12 to 24 hour period. There will most likely be some starch and other nutrient loss to the water, but not to a level that anyone notices
