How long does homemade giardiniera last?
Properly stored in an airtight jar in the refrigerator, giardiniera keeps for 2–3 weeks. The flavor deepens after a few days.
Can I make giardiniera without vinegar?
Vinegar is essential for preservation and the characteristic tang. You cannot safely omit it; use white or apple cider vinegar as substitutes.
Do I need to sterilize jars for giardiniera?
Since this is refrigerated (not shelf-stable), standard clean jars are sufficient. Wash in hot soapy water or run through the dishwasher.
Can I add other vegetables to giardiniera?
Yes. Zucchini, green beans, onions, or mushrooms work well. Keep pieces uniform in size for even pickling.
Should I blanch the vegetables first?
No blanching needed. Raw vegetables pickle directly in the hot vinegar brine and retain their crisp texture.
