Step 1

Combine first 6 ingredients in saucepan. Bring mixture to boil, stirring until sugar dissolves. Reduce heat to medium; simmer until mixture is reduced to 3 1/2 cups, 20 to 25 minutes. Strain into 4-cup measuring cup; cool to room temperature. Stir in vinegar and vanilla. Pour into twelve 1/3-cup ice pop molds. Insert ice pop covers and sticks; freeze overnight.

Step 2

Small paper cups can be used instead of ice pop molds. Pour the mixture into the paper cups, partially freeze, then insert a wooden stick into the center of each and freeze overnight. If pops are difficult to remove from cups, cut a slit in each cup with scissors, then peel it off.
