How do you turn liquid into slush?

Turning liquid into slush can be a fun science experiment or a tasty way to make frozen drinks. With just a few simple ingredients and techniques, you can easily transform ordinary liquids into an icy slurry perfect for chilling beverages or making homemade snow cones.

What is slush?

Slush, also sometimes called slurry, is a semi-frozen mixture with a soft, fluid consistency. It’s composed of tiny ice crystals suspended in a liquid. The icy crystals make the mixture thick and spoonable, while the liquid gives it a fluid, pourable texture.

Slush falls somewhere in between a fully liquid state and a solid frozen state. It’s often created by partially freezing a liquid like fruit juice, soft drinks, alcohol mixes, or just plain water.

Slush has a soft, crunchy texture from the small ice grains. It also tends to be quite cold but not rock solid like ice cubes. This makes it great for chilling drinks without diluting them too much.

Uses for slush

Slush has many fun and practical uses, including:

  • Slushy drinks like frozen margaritas, daiquiris, or lemonade
  • Snow cones or Hawaiian shave ice
  • Granitas made from coffee, fruit juices or wine
  • Soft-serve ice cream mixes
  • Smoothie bowls with a thick, frozen topping
  • Chilling wines and cocktails without diluting
  • Science experiments to learn about states of matter
  • Play “snow” for kids on hot days

The soft, spoonable texture of slush makes it perfect for drinks and cold desserts. It’s also a fun sensory material for children to play with.

How to Make Slush

There are a few easy methods to turn liquid into slush:

Method 1: Freeze and scrape

One of the simplest ways to make slush is to partially freeze a liquid then scrape it. Here’s how:

  1. Pour any liquid into a shallow metal pan or glass baking dish. Fruit juices, soft drinks, alcohol mixes, and water all work well.
  2. Place the pan or dish in the freezer for 1-2 hours. Check it periodically until the edges start to freeze but the middle still has a fluid consistency.
  3. Remove from the freezer and use a fork to scrape and churn the partially frozen mix. This breaks up the ice crystals and incorporates air to create a uniform slushy texture.
  4. For more flavor and sweetness, you can add sugar, honey, fruit, or even small candies like gummies before initially freezing.

The freeze and scrape method creates a basic slush with minimal effort. It’s great for making Italian ice, granitas, snow cones, and even homemade Gelato.

Method 2: Blender

You can also use a blender to turn liquid to slush. Here’s how:

  1. Pour your liquid into ice cube trays and freezer overnight.
  2. Add the frozen cubes and any flavorings to a high-powered blender.
  3. Blend, stopping to stir occasionally, until a smooth icy slush forms.
  4. For thicker slush, add less liquid. For a thinner consistency, add more liquid as you blend.

Using a blender makes it easy to create a fine-grained slush with a thick, spoonable texture. It’s great for slushy cocktails, smoothie bowls, and desserts.

Method 3: Ice cream maker

You can also use an ice cream maker to churn liquid into slush. Here’s how:

  1. Prepare your liquid mixture and refrigerate until chilled. Good bases include fruit purees, juices, coconut milk, sweetened condensed milk, or cream.
  2. Pour the chilled mixture into your ice cream maker.
  3. Turn on the machine. Churn for 20-30 minutes until the mixture has a thick, softly frozen slushy texture.
  4. For more flavor, add spices, extracts, citrus zest, or other mix-ins after 10 minutes of churning.

Using an ice cream maker makes it easy to create a flavorful slush with a perfectly smooth, spoonable texture. It’s great for Italian ices, cocktails, and adult milkshakes.

Tips for Making Slush

Here are some handy tips for turning out great slush:

  • Use liquids with a high water content like fruit juices, sweetened drinks, alcohol mixes, milk, or coconut milk. Avoid thick liquids like heavy cream.
  • Chill the liquid mixture well before freezing for faster, smoother results.
  • Add salt to lower the freezing point, creating slush at higher temperatures.
  • Use simple syrup or sugar to add sweetness and texture.
  • Flavor with extracts, herbs, citrus zest, ground spices, alcohol, or fruit purees.
  • Add a pinch of instant coffee or espresso powder for richness.
  • Stop freezing while the mixture is still a bit soupy to allow it to fully thicken into slush.

Common Problems and Solutions

Having trouble getting the perfect slushy texture? Here are some common issues and how to fix them:

Problem Cause Solution
Too liquidy and won’t freeze High alcohol or sugar content
Using heavy cream as base
Reduce alcohol to under 15%
Use lighter liquids as base
Grainy or icy texture Freezing too fast
Letting slush melt and refreeze
Freeze mixture more slowly
Break up ice crystals as slush melts
Diluted, icy drinks Using slush with high water content Drain off excess liquid before serving slush
Flavors seem muted Numbing effect of cold
Using alcohol in base
Add extra flavorings
Reduce alcohol percentage

Troubleshooting the texture and flavor will help you end up with the perfect slush for drinks, desserts, or science experiments.

Fun Slush Flavor Ideas

Slush is great because you can flavor it with almost any liquid. Here are some fun flavor ideas to try:

  • Fruit flavors: Mango, strawberry, lemon, lime, pineapple, banana, cherry, peach
  • Other sweet flavors: Root beer, cola, butterscotch, vanilla, chocolate, coffee, mocha
  • Savory flavors: Bloody Mary, margarita, pina colada, white russian, mint julep, spicy mango margarita
  • Adult flavors: Piña colada, strawberry daiquiri, sangria slush, margarita, mimosa, Irish cream
  • Nostalgic flavors: Blue raspberry, tiger’s blood, cotton candy, bubblegum, banana

Feel free to mix and match flavors. Blend fruits together, add cookies or candy, and top with whipped cream once served. The possibilities are endless for homemade slush flavors!

Slush vs. Other Frozen Treats

So how does slush differ from other frozen desserts? Here’s a quick comparison:

Treat Texture Serving Temperature
Slush Soft, spoonable, semi-frozen Very cold but not frozen solid
Granita Light, flaky ice crystals Frozen and served semi-frozen
Sorbet Smooth, creamy Frozen
Snow cone Fluffy shaved ice Very cold and crunchy
Ice cream Rich, creamy Frozen

Slush has a unique soft, wet, spoonable consistency unlike the finer texture of granita or heavier creaminess of ice cream. It’s cold like a snow cone but doesn’t have the same light, crunchy shards of ice.

Popular Slushy Treats

Slushies make great summertime treats. Here are some of the most popular slushy desserts and drinks to try:

Snow Cones

These brightly colored, flavorful mounds of icy slush are a favorite cooling treat. Popular flavors include tiger’s blood (watermelon, strawberry, and coconut) and banana.


An Italian slush made by freezing and scraping juices, coffee, wine, or other liquids into a grainy frozen mixture. Often served in a cup or paper cone.

Hawaiian Shave Ice

Tropical flavors like mango, guava, and pineapple shaved into a giant mound of fluffy slush. Often topped with fruit, condensed milk, or azuki beans.

Slush Puppies

This famous brand of slushie available at concession stands, often in fun flavors like blue raspberry, root beer float, and sour apple.


Blended margaritas turn the classic cocktail into a boozy slushie, perfect for staying cool by the pool.
