I forgot about this bag of potatoes in the pantry and they had started growing sprouts.

A few small sprouts on a potato are typically safe, provided you remove them before cooking. However, if the sprouts cover a significant portion of the potato, it indicates advanced growth and possibly higher toxin levels. Visual red flags include multiple large sprouts, extensive greening of the potato skin, and soft or shriveled spots on the potato.

If the potato has more sprout than flesh or feels soft and spongy, it is beyond salvaging. These conditions not only suggest elevated toxin levels but also a degradation in quality and taste, making the potato less desirable for consumption.

5. Does Snapping Off The Sprouts Make The Potato Safe Again?

Removing the sprouts from a potato can help reduce the risk of consuming increased levels of solanine. By snapping off the sprouts and discarding them, you remove the primary source of concern. However, this does not reduce solanine levels that may have developed in the potato flesh itself if the tuber has also turned green or has extensive sprouting.

While removing sprouts can make the potato safer to eat, it’s important to assess the overall condition of the potato. If there are no additional signs of spoilage or greening, the potato can be cooked and consumed safely. However, caution should be exercised if there is any doubt about the potato’s safety.

6. Green Patches, Soft Spots, And Odd Flavors: When To Toss The Potato

Green patches on a potato indicate increased solanine levels. The chlorophyll that gives the green color is not harmful, but its presence often accompanies higher concentrations of glycoalkaloids like solanine. If you notice green patches, it’s best to cut them off or, if they are extensive, discard the potato entirely.

Soft spots and an off-putting smell or flavor are also signs that a potato has gone bad. These changes can indicate spoilage or microbial growth, making the potato unsafe to eat. If the potato exhibits any of these characteristics, it is best to throw it away.

7. Does Baking Destroy Solanine Or Other Potato Toxins?

Baking or cooking potatoes does not significantly reduce solanine levels. Solanine is heat-stable, meaning it does not break down easily at the temperatures typically used in cooking. Therefore, baking, boiling, or frying potatoes will not eliminate the risk of toxicity from solanine if it is present in high concentrations.

To minimize the risk, it is crucial to start with potatoes that are not heavily sprouted or green. If in doubt, it’s safer to discard potentially toxic potatoes rather than relying on cooking to make them safe.
