Expiration & Storage Tips
When does jerusalem artichoke expire?
Fresh Jerusalem artichokes can last up to 2 weeks in the refrigerator if stored properly. Once cooked, they should be eaten within three days if refrigerated, and can last up to a year if frozen properly. When stored unopened in a can, they will remain good well past the printed expiration date (up to a year), but after opening, they should be transferred to a resealable container, refrigerated, and consumed within 3-4 days.
How do you tell if jerusalem artichoke is bad?
Spoiled Jerusalem artichokes usually develop dark spots, similar to potatoes. The texture could also change – they may feel soft or slimy, and could have a sour smell. Another sign of spoilage is the growth of molds. Do not consume if these signs are noticed, it's better to play safe and toss it out.
Tips for storing jerusalem artichoke to extend shelf life
• Store fresh Jerusalem artichokes in a cool, dark place, like a pantry, as soon as you bring them home. Place them in a paper bag to absorb excess moisture and ethylene gas, which can make them ripen more quickly.
• For a longer shelf life, store Jerusalem artichokes in the refrigerator’s vegetable crisper drawer, inside a perforated, plastic bag.
• If you've cooked Jerusalem artichokes, allow them to cool completely then store in an airtight container in the refrigerator. For a longer period, store in freezer-safe containers and freeze.
• For canned Jerusalem artichokes, always check the can before opening. If it's swollen, dented, or damaged in any way, don't use it. After opening, transfer any leftovers to a resealable container, refrigerate and consume within 3-4 days.
