Ingredients

  • 8 cups thinly sliced sweet onions
  • 2 tablespoons canning salt
  • 1-3/4 cups white vinegar
  • 1 cup sugar
  • 1 teaspoon dried thyme

Directions

  1. Place onions in a colander over a plate; sprinkle with canning salt and toss. Let stand 1 hour. Rinse and drain onions, squeezing to remove excess liquid.
  2. In a Dutch oven, combine vinegar, sugar and thyme; bring to a boil. Add onions and return to a boil. Reduce heat; simmer, uncovered, 10 minutes. Remove from heat.
  3. Carefully ladle hot mixture into four hot half-pint jars, leaving 1/2-in. headspace. Remove air bubbles and adjust headspace, if necessary, by adding hot mixture. Wipe rims. Center lids on jars; screw on bands until fingertip tight.
  4. Place jars into canner with simmering water, ensuring that they are completely covered with water. Bring to a boil; process for 10 minutes. Remove jars and cool.
