Ingredients to make Watermelon Lemonade
You will need a blender to puree the watermelon, and you’ll need to make a simple syrup.
Simple syrup is very simple to make. You can even do it in the microwave. It’s equal parts water and sugar. I just melt a cup of sugar in a cup of water in the microwave for a couple of minutes. If you want to cut the sugar in this drink, you can make a simple syrup using equal parts water and Splenda.
Here’s what you need:
- 1/4 of a seedless watermelon, cubed
- 1 cup of fresh squeezed lemon juice
- 4 cups water
- simple syrup with 1 cup water and 1 cup sugar
- Lemon slices
- Watermelon slices

My father-in-law died a few months ago. With that, my mother-in-law has made some big changes, including moving out of their home. Lately, she’s been bringing things by to see if we wanted them. You should have seen the giant Santa Claus Christmas ornament she brought — like the size of a basketball!
One thing she brought me was this super heavy duty blender, some knock off version of a Vitamix.

My mother-in-law said he was only able to use it one time. She brought it over and gave it to us as she had no use for it. It looked pretty fancy, so I decided to keep it. I looked it up on Amazon and this is one heavy duty blender. You can even make soup in it! I don’t know much about it, but I think it’s fairly close to a Vitamix — about as close to a Vitamix as I’ll ever get.
It did really well with pureeing watermelon. Now, I’ve been making smoothies full of fresh fruit and greek yogurt for Nate to drink on the way to work. Seriously, I can cut open a peach, pull the seed out, and throw the entire thing in there and it just purees! I love this thing!
