MACERATE STRAWBERRIES: Place 4 cups fresh strawberries, washed and hulled in a medium bowl and sprinkle with 2 tablespoons granulated sugar. Toss to coat and let sit for 30 to 60 minutes until the strawberries release their juices.
BLEND MIXTURE: Add the strawberries and their juices to a blender. Add 2 tablespoons balsamic vinegar and 1/8 teaspoon fresh ground black pepper. Pulse until a slightly chunky puree forms.
FILL MOLDS: Pour the mixture evenly into popsicle molds, leaving about ¼ inch of space at the top.
INSERT STICKS: Cover the molds with lids or aluminum foil and insert popsicle sticks.
FREEZE: Freeze for at least 12 hours, or until completely frozen.
SERVE: Run warm water over the outside of the molds for about 10 seconds to release the popsicles. Serve immediately.
