With soap and water wash the lemons. Cut lemons into fourths and place in a high speed blender.
Add water to the cut lemons and blend on high for 20 seconds.
With a wire strainer and a large bowl, strain the blended lemon into the large bowl. The bowl will now contain delicious lemon water, and the strainer will have the blended lemon remains. Discard the lemon remains.
Rinse out the remaining lemon in the blender until clean. Pour the lemon water from the large bowl back into the blender.
Add raspberries and sugar and blend until well mixed. Lemonade will turn a deep pink.
Chill and serve.
Notes
I love a tarter lemonade. If you prefer a sweeter homemade lemonade, add ¼ cup sugar, or less, at time. Test until preferred sweetness.
For a zippier taste, use 5 lemons.
Add ice to have a colder drink, keep in mind it will water down the original flavor.
