Cold Vidalia Onion Dip with Vinegar

This make-ahead dip starts with sweet Vidalia onions soaking overnight in a sugar and vinegar brine that tames their sharpness.

By morning the onions have mellowed into tender, tangy ribbons that mix with mayonnaise and celery seed into a creamy spread.

The sweet-sour balance makes it addictive on buttery crackers, and the overnight prep means zero last-minute work before your party.

Make-Ahead Tips

• Soak the onions a full 8-12 hours for the best texture; they’ll soften completely and lose their raw bite
• Drain the onions thoroughly before mixing with mayonnaise or the dip will be too thin
• Adjust the mayonnaise amount to reach your preferred consistency; start with less and add more as needed
• Make the dip a day ahead and refrigerate; the flavors meld beautifully and it actually tastes better the next day
