What Makes This Recipe So Good

- Fast and foolproof: Toss everything in a blender and you’re done in minutes.
- Balanced flavor: Blue raspberry brings candy-like sweetness while fresh lemon juice keeps it bright and zippy.
- Customizable sweetness: You control the sugar, so it’s not cloying like some store-bought slushes.
- No special equipment: A standard blender and some ice are all you need.
- Kid-friendly and party-ready: The color is fun, and you can batch it for a crowd or spike it for adults.
Ingredients
- 1/3 cup blue raspberry syrup (store-bought snow cone syrup or homemade)
- 1/3 cup freshly squeezed lemon juice (about 2–3 lemons)
- 1–1 1/4 cups cold water (start with 1 cup and adjust)
- 2–3 tablespoons granulated sugar or honey (optional, to taste)
- 4 cups ice (crescent or cubed)
- Pinch of salt (enhances flavor)
- Lemon slices (for garnish, optional)
- Fresh berries or mint (optional garnish)
Instructions

- Add blue raspberry syrup, lemon juice, 1 cup of cold water, sweetener (if using), and a pinch of salt to the blender.
- Blend briefly to combine, then add the ice.
- Blend on high until the mixture looks thick and smooth, about 20–40 seconds. If your blender stalls, stop and pulse to break up the ice.
- Check texture.
If it’s too thick, add a splash of water and blend again. If it’s too thin, add a handful of ice and blend.
- Taste and adjust sweetness or lemon juice. You want a bright, tangy finish with a clean sweet note.
- Pour into chilled glasses.
Garnish with lemon slices, a few berries, or a sprig of mint.
- Serve immediately while it’s frosty and thick.
How to Store
Slush is best enjoyed right after blending. If you need to hold it, transfer the mixture to a freezer-safe container and freeze for up to 1–2 hours. Stir or re-blend with a splash of water before serving to loosen the texture.
For make-ahead convenience, freeze the base (everything except the ice) in an ice cube tray.
When ready, blend the flavor cubes with fresh ice and adjust water to reach your preferred consistency.

Why This is Good for You
- Hydration: Crushed ice and water help you stay hydrated on hot days.
- Vitamin C: Fresh lemon juice adds a solid dose of vitamin C for immune support and brightness in flavor.
- Lower sugar control: You decide how much sweetener to add, which keeps it lighter than many store-bought slushes.
- Mindful indulgence: It satisfies a sweet craving without heavy dairy or artificial creamers.
Pitfalls to Watch Out For
- Too much water: Overwatering turns the slush soupy. Add water gradually until it blends smoothly.
- Insufficient ice: Not enough ice leads to a thin texture. Keep extra ice on hand to adjust.
- Over-blending: Running the blender too long warms the ice and thins the slush.
Blend just until smooth.
- Overly tart or sweet: Taste and adjust. A little extra lemon or a teaspoon of sugar can fix the balance quickly.
- Weak lemon flavor: Bottle lemon juice can taste flat. Freshly squeezed makes a big difference.
Variations You Can Try
- Blue Raspberry Coconut: Replace half the water with light coconut water for a tropical twist.
- Sparkling Slush: Use chilled lemon seltzer for part of the water.
Blend with still water, then stir in the bubbly at the end to keep the fizz.
- Berry Boost: Add 1/2 cup frozen blueberries or raspberries for extra fruit flavor and color depth.
- Electrolyte Version: Swap some water for a lemon-lime electrolyte drink for post-workout refreshment.
- Adult Upgrade: For grown-ups, add 1–1.5 ounces of vodka, white rum, or tequila per serving. Blend lightly to avoid over-thinning.
- Sugar-Free: Use a sugar-free blue raspberry syrup or a few drops of blue raspberry flavoring plus your favorite zero-calorie sweetener.
- Herbal Lift: Muddle a few mint leaves or basil before blending for a fresh, garden note.
FAQ
Can I make this without blue raspberry syrup?
Yes. Use a neutral simple syrup and add a few drops of blue raspberry flavoring, or blend 1/2 cup frozen blueberries with lemon juice and sweetener for a natural color and a similar vibe.
The flavor won’t be exactly the same, but it’s still bright and refreshing.
What if I don’t have a powerful blender?
Crush the ice in batches by pulsing, or wrap it in a clean towel and tap it with a rolling pin to break it down before blending. Add water a tablespoon at a time until your blender runs smoothly.
How do I keep the slush thick longer?
Chill your glasses, ingredients, and even the blender jar if you can. Use plenty of ice and avoid over-blending.
You can also add a small handful of frozen fruit to help maintain body without extra water.
Is there a way to make it less sweet?
Absolutely. Start with no added sweetener and taste after blending. The lemon juice keeps it lively, so you may find you need less sugar than you think.
Can I batch this for a party?
Yes.
Multiply the ingredients and blend in waves. Keep a pitcher of the base (without ice) chilled in the fridge and blend with fresh ice as guests arrive for the best texture.
What kind of blue raspberry syrup should I buy?
Look for snow cone or drink syrups labeled “blue raspberry.” If you prefer fewer additives, choose a brand with shorter ingredient lists, or make a quick homemade version with sugar, water, lemon zest, and flavoring.
Can I use crushed ice from my freezer dispenser?
Definitely. Crushed ice blends faster and gives a smoother slush.
You may need slightly less water since it integrates more quickly.
Final Thoughts
This Frozen Blue Raspberry Lemonade Slush is simple, bright, and wildly satisfying. It’s the kind of treat that feels special without any fuss. Keep lemons, blue raspberry syrup, and a bag of ice on hand, and you’re minutes away from something cool and fun.
Make it exactly how you like it—more tart, less sweet, with bubbles or berries—and enjoy that icy, electric-blue sip of summer anytime you want.
