Add the diced strawberries and 2 T. granulated sugar into a blender. Blend until completely smooth.
Add to a 10 cavity popsicle mold being careful not to spill the strawberry puree down the sides.
Place in the freezer for 30 minutes.
In a small saucepan, add in the water and remaining sugar. Heat over medium just until the sugar is dissolved. This should take about 3 minutes of simmering.
Pour the lemon juice in with the simple syrup and stir.
Using a funnel, fill the remaining popsicle molds with lemonade.
Soak the wooden popsicle sticks in water for 1 - 2 minutes.
Add the popsicle sticks to the mold. Place in the freezer for at least 8 hours to overnight.
Run the popsicle mold under warm water for about 20 seconds to release the popsicles. You can run them under water longer if the popsicles won't release from the mold on the first try.
If you have a different mold and want to use wooden popsicle sticks instead of the plastic tops provided, cover the top of the mold with heavy duty tin foil or press and seal. Cut small holes and add the popsicle sticks in.
Soak your wooden popsicle sticks in water before putting them into the popsicles.
Run the bottom of the mold under warm water for about 20 seconds making sure the warm water gets on all of the cavities. You can do it an additional 10 seconds if needed.
Lastly, remove the popsicles from the mold and cover each one with plastic wrap or press and seal. Pop them in a freezer bag until you’re ready to enjoy one or 3.
