Bring 2 cups of water and sugar to a boil, just to dissolve the sugar. Allow sugar mixture time to cool.

Microwave the lemons, three at a time for 20 seconds.

Remove the lemons from the microwave and roll them on the kitchen counter, pressing down with the palm of your hand to break the pulp up inside. Then, cut the lemons in half and juice the lemons.

Add two cups of cold water to the sugar mixture.

Then, add the lemon juice. Use a fine wire strainer to add the lemon juice-to remove any small seeds or pulp.

Now, place 2 1/2 cups of the homemade lemonade in a blender with the 2 1/2 cups of fresh blueberries. Blend to crush the blueberries.

Add the blueberry mixture back into the lemonade through the fine wire strainer to remove the the blueberry pulp.

Chill and serve with ice, slices of lemon and extra blueberries, if desired.
