Why This Recipe Works
- It uses a full cup of blue raspberry syrup for maximum flavor. Yes, a whole cup goes into one pitcher. Just go with it.
- There’s no need to dirty an extra pot cooking down a syrup from scratch. This drink gets plenty sweet and flavorful just by blending everything.
- Using four cups of ice makes for an extra thick, extra impressive slushie that’s sure to win over any crowd. But I’ll include notes below for a lighter version, a single-serving portion, or a boozy twist.
Ingredients
- 4 cups ice cubes
- 1 cup blue raspberry drink mix or blue raspberry syrup (such as Kool-Aid or a snow cone syrup)
- 1 cup cold water
- 1/4 cup granulated sugar (adjust to taste)
- 1 tablespoon fresh lemon juice
- Optional: whipped cream and blue sprinkles for garnish
Why these ingredients matter: Well, the ice is the base of this drink and is what gives you that thick, slushy consistency.
Blue raspberry syrup has the candy flavor; it’s punchier than juice and gives the drink its iconic color.
Sugar rounds out the tartness, while lemon juice adds just enough brightness to keep the sweetness from feeling flat.
Cold water thins the mixture just enough for your machine to actually move the ice around.
Instructions
Add the ice cubes to a high-powered blender first. Starting with the ice on the bottom helps everything process more evenly instead of leaving chunks at the top.
Pour in the blue raspberry syrup, cold water, sugar, and lemon juice.
Blend on high for 30 to 45 seconds, pausing to scrape down the sides as needed, until the mixture is completely smooth with no solid chunks remaining.
Taste and adjust sweetness, adding a touch more sugar or syrup if you’d like it stronger.
Pour into glasses right away and top with whipped cream and blue sprinkles if desired. Serve immediately for the best texture.
Making It in a Ninja Slushi Machine
For my readers with a Ninja Slushi machine, this recipe is soo easy for you to make.
Just add the water, syrup, sugar, and lemon juice directly to the machine’s tank. The machine will freeze and churn the liquid.
Select the “Slushi” or “Frozen Drink” setting and choose your desired consistency level. The Ninja will spin and freeze the mixture over the next couple of hours, thickening into slush.
Once it reaches your preferred thickness, dispense directly from the tap into glasses and serve right away. If you’d like it thicker, let it run through an extra cycle before dispensing.
Storage
This drink is best enjoyed fresh, but you can pour leftovers into a freezer-safe container and freeze for up to 2 weeks.
To serve again, let it sit at room temperature for 5 to 10 minutes, then break it up with a fork or re-blend briefly to restore the texture.
Again, for my Ninja Slushi machine friends, most models allow you to keep the mixture in the tank on a hold or “keep frozen” setting for easy re-dispensing later.
Substitutions
- No blue raspberry syrup? Blue Gatorade or blue Powerade work in a pinch.
- Prefer less sugar? Use a sugar-free drink mix or cut the sugar in half.
- Want it fizzy? Replace the cold water with lemon-lime soda for a bubbly twist.
FAQ
What gives blue raspberry its flavor?
Blue raspberry isn’t a real fruit — it’s an artificial flavor originally created to set red fruit drinks apart from similar-tasting ones, using a blue dye borrowed from a type of honeysuckle berry.
Why is my slushie watery instead of thick?
This usually happens when there isn’t enough ice relative to liquid, or when the ice isn’t crushed finely enough. Add more ice a little at a time and blend in short bursts.
Can I make this without a blender or machine?
Yes. Freeze the liquid mixture (minus the ice) in a shallow dish for 2 to 3 hours, scraping it with a fork every 30 minutes to create fine crystals, similar to a granita.
Is blue raspberry syrup the same as blue curaçao syrup?
No. Blue raspberry syrup is a non-alcoholic, sweet flavoring syrup, while blue curaçao is typically an alcoholic liqueur, though a non-alcoholic version does exist for mocktails.
