Savory Blueberry-Onion Jam

Directions

• In a Dutch oven, heat oil over medium heat. Add onions, tarragon, thyme, salt and pepper. Reduce heat to medium-low; cook 30-35 minutes or until liquid is evaporated, stirring occasionally.
• Add blueberries, honey, vinegar and lemon juice; bring to a boil. Reduce heat; simmer, uncovered, 50-55 minutes or until mixture is thickened, stirring occasionally. Remove from heat.
• Carefully ladle hot mixture into six hot half-pint jars, leaving 1/4-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.
• 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.
