❓ 10 FAQs

1. Can I use white or yellow onions?
Yes—but red onions give the best color and sweet-tangy flavor.

2. Do I have to boil the brine?
Yes—hot brine helps soften onions and infuse flavors quickly.

3. How soon can I eat them?
They’re tasty after 30 minutes, but best after 1–2 hours.

4. Are they shelf-stable?
No—store in refrigerator only; they’re not canned for long-term storage.

5. Can I reuse the brine?
No—discard after finished for food safety and best flavor.

6. Why are my onions soft?
Longer pickling makes them softer; they’re crispest when eaten within a few days.

7. Can I make them sugar-free?
Yes—omit sugar or use a sugar substitute, but flavor will be more tart.

8. Do I have to slice them thin?
Thin slices pickle faster; thicker slices will need longer.

9. Can I use red wine vinegar?
Yes—it gives a deeper, more robust flavor.

10. What dishes pair best with pickled onions?
