Equipment

Blender: I stick with a standard countertop blender to crush the ice and blend everything together.
Measuring cups and spoons: Getting the measurements right helps each flavor come through and keeps the texture slushy, not watery.

Tall glasses: I love serving this in clear glasses to show off that electric blue color.
Spoon or straw: A thick straw works best, but sometimes I just use a spoon to scoop up the icy bits.
Ice cube tray: I usually freeze my own ice for the freshest cubes.

Ingredients

2 cups ice cubes fresh ice makes the best texture
3/4 cup cold water
1/2 cup blue raspberry syrup store-bought or homemade, either works
1/4 cup lemon-lime soda I usually grab Sprite or something similar

1 tablespoon fresh lemon juice optional, for a little extra tartness
Blue food coloring optional, if I want a deeper blue shade
Fresh raspberries or lemon slices for garnish

Instructions

I fill the blender with ice cubes.
Next, I pour in the cold water and blue raspberry syrup.
If I’m feeling bold, I’ll add a few drops of blue food coloring for a brighter blue.

Then I blend on high speed until the ice is totally crushed and the mix looks nice and slushy.
I pour in the lemon-lime soda and lemon juice (if I’m using it), then pulse the blender a few more times to mix it all up.
I pour the slushie into tall glasses right away.

For garnish, I usually toss in some fresh raspberries or a lemon slice before serving.

Notes

I always serve the slushie right after blending. The ice melts pretty quickly, and the drink loses its texture if it sits too long.

If the slushie turns out too thick, I’ll add a splash more soda or water and blend again. If it’s too runny, a handful of extra ice cubes fixes it.

Sometimes I want it sweeter, so I add a little more syrup. If I’m in the mood for a sharper bite, I’ll squeeze in extra lemon juice.

There are sugar-free syrups and diet sodas out there if I want a lower sugar mocktail. I try not to let the ice sit around before blending, since it can clump up and mess with the texture.

I keep leftover blue raspberry syrup in the fridge, tightly closed, so it’s ready for next time.

Tasting Notes

When I take a sip of this blue raspberry slushie mocktail, the first thing I notice is that striking blue color. It just looks so inviting and cool in the glass.

The flavor is sweet with a clear berry taste. There’s a blend of raspberry notes, balanced by a bit of tartness.

The texture is smooth and icy. It melts quickly on my tongue and leaves a refreshing feeling—kind of addictive, honestly.

Key flavor highlights:

Sweet berry taste
Mild tart sensation
Refreshing finish

I find the aroma gentle, mostly fruity. It’s not overpowering, just pleasant and light.

As the ice melts, the flavor gets a little lighter. Still, the drink stays enjoyable, even as it warms up a bit—maybe even more so?

Substitute

When I don’t have blue raspberry syrup handy, I try out a bunch of different options to keep the flavor interesting.

Ingredients I sometimes use as substitutes:

Blue sports drink (like blue Gatorade)
Lemon-lime soda and a bit of blue food coloring
Pineapple juice with a drop of blue food coloring

Blueberry juice mixed with simple syrup

If I’m hoping to dodge artificial colors, I’ll blend up some blueberries and strain the mixture. A splash of lemon juice gives it a little zing, too.

The color isn’t quite as bright as the syrup, but honestly, it’s a pretty natural blue and tastes great.

Equipment Needed for Substituting:

Blender
Strainer (for fresh fruit juice)
Measuring spoons

Instructions for Using a Substitute:

Blend or mix your chosen substitute ingredient until smooth.

Strain if needed.
Mix into the slushie in the same amount you would use for blue raspberry syrup.

If I’m using soda or juice, I usually toss in a bit more ice. That way, the slushie keeps its thick, frosty texture—nobody wants a watery drink, right?
