Put lemon juice, cucumber, dill, sugar (start with ¾ cup – you can add more later if you want it sweeter), ice and about 1 cup of water in a blender. Blend for about a minute. Pour into a pitcher and mix with the rest of the water. Taste and add more sugar if desired. If I add more sugar, I pour some of the lemonade back into the blender and add the sugar to that, whirl for a few seconds and then stir it into the rest of the mixture.
Pour over ice, garnish with any, all or none of the optional garnishes and enjoy!
