Directions

1. 1

   Toss the sliced onions, vinegar, salt, and Pickling Spice together in a large bowl until every slice is coated.

2. 2

   Let the mixture sit at room temperature for about an hour — the onions should soften slightly and deepen into a bright pink.

3. 3

   Transfer everything to a sealable jar and top off with a little more vinegar, if needed, to fully cover the onions.

4. 4

   Refrigerate for at least 24 hours before serving to let the flavors come together.

5. 5

   Keep refrigerated and enjoy within a couple of weeks. Makes about 1 quart.

6. 6

   Serving suggestions: pile onto burgers, tacos, grilled meats, or pizza. They’re also a tangy lift in salads, grain bowls, and wraps.
