Potatoes will sprout when the conditions are right.
If your spuds are in a well-lit area of the kitchen, in a basket with onions or on the counter after spending time in the refrigerator, they'll end up with "eyes."
It might be tempting to store your potatoes in the coldest place in the house to avoid this, but you should never store potatoes in the fridge.
The starches can convert to sugar and produce dangerous chemicals when cooked.
If your potatoes have just begun to sprout, you may still be able to salvage them by cutting off the sprouted areas with a kitchen knife or potato peeler.
If there are several large sprouts and the potatoes appear shriveled or wrinkled, toss them.
That's because the sprouts are a sign that your potatoes contain higher levels of unsafe toxins than fresh ones do.
