What You’ll Need
- 1 1/2 cups flat grape soda (chilled)
- 2 cups ice cubes
- 1 tablespoon fresh lemon juice
- Lemon slices, for garnish (optional)

Why This Recipe Works (Quick Science)
- Flat soda blends better: No fizz means the blender doesn’t explode and you get a super smooth texture.
- Lemon juice’s acid cuts the sweetness, so it tastes more like “real grape” than candy.
- Blending ice with the soda makes the whole drink thick and frosty—way more fun than just pouring over ice.
Common Mistakes
- Using fresh bubbly soda: It’ll fizz up and spill out of the blender—let it go flat first!
- Adding too much ice: This waters down the flavor, so measure carefully.
- Not chilling the soda: Warm soda melts the ice too fast and makes the slushie runny.
- Not enough lemon: Without the lemon, it can be super sweet—don’t skip it!
What to Serve With
- Pizza or cheesy breadsticks
- Hot dogs or corn dogs
- Popcorn or kettle corn
- Grilled cheese sandwiches
- Fresh fruit (like grapes or melon)
Pro Tips
- Chill everything first: Cold soda and cold ice = best slushie texture.
- Use flat soda: Leave the cap off for a couple hours or pour and stir to speed it up.
- Adjust lemon to taste: Start with a tablespoon, then add a little more if you like it tangier.
- Serve right away: Slushies melt quickly, so blend and pour when you’re ready to drink.
- Try with other sodas: This works with orange soda or root beer too!
Tools You’ll Need
- Blender
- Measuring cups and spoons
- Glasses for serving

Substitutions & Variations
- Use diet grape soda if you want to cut down the sugar.
- Add fresh grapes for a chunkier slush.
- Swap lemon for lime juice for a twist.
- Try with orange, strawberry, or cherry soda—the method is the same!
- Make it grown-up: Add a splash of vodka for a party drink.
Make Ahead Tips
- You can flat and chill the soda ahead of time, but don’t blend until right before serving for the best icy texture.
