We stored our Jerusalem artichokes in the fridge at approximately 40°F (4°C) and monitored them over a three-week period, both opened and unopened. After 14 days, we began our observations, noting any soft spots, mold, or wrinkling on the surface. We recorded that some artichokes developed slight wrinkling and a few had soft spots, while others remained firm and smooth. To verify safety, we cooked a sample to 165°F (74°C) and checked for any off-putting smells or changes in texture. Ultimately, we discarded anything that showed signs of spoilage, prioritizing food safety throughout our testing process.
Sunchokes do not have a strict expiration date like some other perishable foods. Instead, they are best consumed within 1-2 weeks of purchase for optimal taste and texture. As sunchokes age, they can become wrinkled, soft, and lose their crispness, which may affect their overall quality. While they may still be safe to eat after this time, their flavor and texture may not be as enjoyable.

One risk associated with sunchokes is their high inulin content, which can cause gas and bloating in some individuals, especially when consumed in large quantities. It is advisable to introduce them gradually into your diet to avoid digestive issues. Additionally, always wash and scrub sunchokes thoroughly before cooking to remove any dirt or debris that may harbor harmful bacteria.
To prolong the freshness of sunchokes, store them in a cool, dark place with good ventilation, such as a paper bag in the refrigerator crisper drawer. Avoid storing them near foods that emit ethylene gas, such as apples and bananas, as this can cause sunchokes to spoil more quickly. If you plan to store sunchokes for an extended period, consider blanching and freezing them to preserve their quality. Before cooking, scrub the sunchokes well under running water or peel them to remove the thin outer skin for a smoother texture.
