Strawberry Watermelon Slushee // Follow Me on Pinterest

This strawberry watermelon slushee is another throwback to my childhood. Like I have mentioned so many times before, a lot of the recipes that I share on this site are from my childhood. My mother was such a fantastic cook and I owe my love of real food and cooking to her.

During the summer, this is one of my favorite drinks to make. It is cold and refreshing and really quenches your thirst. Plus, it’s a cinch to make, so you can stay hydrated and satisfied on the hottest summer days.

Pictures from Childhood and Strawberry Watermelon Slushees // deliciousobsessions.comWhen I was a kid, my mom would make this for us after we had been out horseback riding on a hot summer day. Every time I taste it as an adult, I am magically transported back to being a child. Nothing like fond memories to get you through from time to time!

Important Note On Gelatin Types 

When it comes to gelatin, you don’t want any old gelatin off the supermarket shelves. You want to look for 100% grass-fed gelatin from healthy animals. Just like other animal products, quality is important.

That is why I recommend Vital Proteins Grass-Fed Gelatin products and Perfect Supplements products exclusively. I have compared these brand with other brands on the market and the quality far surpasses anything else I’ve tried. I am thrilled to be one of their affiliate partners and support such great products and companies.

Perfect Supplements offers a grass-fed hydrolyzed collagen (cold-soluble) right now and has a gelatin (hot-soluble) in the works for 2016. Read my review of their product here or watch the video below. You can order their own products via their own site here or on Amazon here.

Vital Proteins offers two types of gelatin. The green top (Collagen Protein) is what you need for this recipe and for recipes where you are making gummies, “jello”, etc. The blue top (Collagen Peptides) is cold water soluble and does not thicken or gel like gelatin does. Both are very nutritious, but can’t be used interchangeably. You can order their own products via their own site here or on Amazon here.

  1. I have not made this yet and I am totally regretting that I did not buy that watermelon that was on sale today. This looks totally amazing. After having a long day in the sun has made me crave this even more! I will have to try this soon!!!!

  2. Do you think regular water or water kefir would work too? I don’t have seltzer water but this sounds yummy! Not sure I have frozen strawberries either, so I will try either cherries or blueberries instead.

    • Katherine – Water kefir would be awesome! I have made slushees with WK before and they are tasty. Any fruit would work for something like this too. Enjoy! 🙂

  3. Yum!! I made a similar drink over the weekend with basil in it too and it was so refreshing and crisp! I’m intrigued by your inclusion of gelatin. I’ll have to try that next time! Thanks for sharing!
