Whole potatoes typically require trimming of sprouts, eyes, and blemishes, while baby potatoes usually only need a quick wash as their skin is thin and edible.
When preparing whole potatoes, it's important to remove any sprouts or 'eyes' that have formed. These sprouts contain solanine, a glycoalkaloid that can be toxic in large quantities. Use a paring knife or vegetable peeler to carefully scoop out the eyes. Also, trim away any green spots or blemishes, as these areas can also contain higher concentrations of solanine. If the potato has any damaged or rotten spots, cut those away as well. The goal is to remove any parts of the potato that are not visually appealing or could potentially be harmful.
Baby potatoes, on the other hand, require minimal trimming. Their skin is thin and tender, and it's perfectly safe and nutritious to eat. Simply wash the baby potatoes thoroughly to remove any dirt or debris. If there are any small blemishes or sprouts, you can trim them away, but it's usually not necessary. The main advantage of baby potatoes is their convenience and minimal prep time.
If you're concerned about solanine levels in any potato, store them in a cool, dark, and dry place. Exposure to light can increase solanine production. Discard any potatoes that are excessively green or have numerous large sprouts.
