Strawberry-Thyme Jam

Directions

1. In a Dutch oven, combine strawberries and butter. Stir in pectin. Bring to a full rolling boil over high heat, stirring constantly. Stir in sugar; return to a full rolling boil. Boil and stir for 1 minute. Immediately stir in thyme.
2. Remove from the heat; skim off foam. Ladle hot mixture into nine 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.
