Notes:
This is a refrigerator pickle and not for water-bath canning. Keep onions fully submerged for best quality. Store refrigerated and use within 2 to 3 weeks. Vinegar options include apple cider or red wine vinegar at 5 percent acidity; flavor will vary. For a sharper bite reduce or omit sugar; for milder onions slice thinner and rest 48 hours.

Troubleshooting
Let's talk about the little things that might have you wondering if you did something wrong. Onions floating to the surface? Don't panic - this happens to everyone. Just press them down with a clean spoon or add a small parchment round to keep them submerged.
Too sharp: add a teaspoon more sugar and let sit another day.
Too mild: swap to red wine or cider vinegar next batch, or add a pinch more salt.
Color lightened: normal pigment moves into the vinegar and turns it pink.

Frequently Asked Questions

Do I have to can these
No. This is a refrigerator recipe. Once the vinegar mixture is poured over the onions and cooled, keep jars chilled and enjoy within 2 to 3 weeks.
Which onions work best
Red onions are the classic choice because they give a bright pink color and mild sweetness. Yellow or white onions can be used but taste sharper and look different.
How soon are they ready
They start to taste good after about 30 minutes, but the flavor and color improve after a few hours. Overnight is best.
Can I reduce the sugar
Yes. Sugar balances the sharpness of the vinegar but is optional for safety. Adjust to taste or omit entirely for a tangier onion.
What vinegar should I use
Always use vinegar that is 5 percent acidity. Distilled vinegar keeps the onions bright pink. Apple cider vinegar gives a warmer tint and softer flavor.
Why did the color fade
Color may fade with long storage or very thin slices. Use fresh red onions, chill promptly, and enjoy within a couple of weeks for the brightest color.
