What Is the Sour Slush Rush?

Each slush layer is blended with crushed ice for a fluffy, smooth texture that chills your glass instantly. The flavors are bold and nostalgic—like the best parts of sour candy, cherry popsicles, and blue raspberry punch—but refined just enough with vodka and liqueurs to suit an adult crowd.

How to Make the Sour Slush Rush – Step by Step

Step 1: Blend the Red Slush

Add cherry Kool-Aid (or fruit punch), cherry vodka, grenadine, and crushed ice to the blender. Blend until you reach a smooth slushy consistency. Pour the red slush into the bottom third of each clear cup or glass. Place cups in the freezer for 15 to 20 minutes to firm up the layer before adding the next.

Step 2: Blend the Green Slush

In a clean blender, combine the limeade concentrate, Green Apple Pucker, green apple vodka, and crushed ice. Blend until smooth and thick. Gently spoon or pour the green slush over the frozen red layer. Return the cups to the freezer for another 15 to 20 minutes.

Step 3: Blend the Blue Slush

For the final layer, blend the blue raspberry punch (or Kool-Aid), blue curaçao, lime juice if using, and crushed ice. Blend until the texture is icy and smooth. Gently spoon this blue mixture on top of the green slush layer.

Step 4: Garnish and Serve

Add a sour rainbow belt, gummy candy, or a sugared rim to take it over the top. Serve immediately, or freeze again for up to an hour if making ahead.

What to Serve with This Cocktail

This cocktail is bold and flavorful, so pairing it with food should balance that intensity. Here are some ideas:

Expert Tips for Layering Success

Getting those perfect, distinct layers can be tricky on the first try, but these tips will help you nail it every time:

• Freeze each layer for at least 15–20 minutes before adding the next.
• Use a spoon or spatula to gently spread each layer over the one beneath it.
• Don’t overblend—the slush should be thick enough to hold its shape.
• Use crushed ice for a smoother, more consistent texture.
• If storing in the freezer, let the cup sit out for 5–10 minutes before serving to soften the slush.

Storage and Make-Ahead Options

While this drink is best enjoyed fresh, you can absolutely make it ahead of time for parties or special occasions.

• Blend and freeze each layer in a separate container. Assemble just before serving.
• Or, fully layer the drink in cups and store in the freezer for up to 2 hours. Just thaw slightly before serving to make sure it’s spoonable and smooth.
• Leftovers? Blend everything together into one funky rainbow slush and enjoy it all mixed up.

Frequently Asked Questions

Can I make this cocktail in large batches?
Yes, you can blend each layer in bulk and freeze them separately. Serve from large punch bowls or make-your-own slush stations for guests.

Can kids enjoy a version of this?
Absolutely. Just skip the alcohol and double up the juice or Kool-Aid. It’s a fun, colorful treat for all ages.

How do I prevent the layers from mixing?
Use thick slush consistency and freeze between layers. Pour slowly and use a spoon to control the flow.
