Key Ingredients

• 4 cups cubed seedless watermelon (chilled, or frozen for thicker texture)
• 1–2 cups ice cubes (adjust for desired slushiness)
• 1–2 tablespoons lime juice (fresh-squeezed is best)
• 1–2 tablespoons sugar, honey, or agave (optional, to taste)
• Optional for garnish: Fresh mint, extra lime wedges, or small watermelon cubes

Equipment You’ll Need

• Blender (any standard blender works; high-powered for smoothest results)
• Sharp knife and cutting board
• Measuring cups and spoons
• Pitcher or jug (if serving a crowd)
• Glasses and straws for serving

Step-by-Step: How to Make Watermelon Slushie

1. Prepare Your Watermelon:
   Choose a ripe, seedless watermelon for the sweetest slushie. Cut into chunks and remove any stray seeds. For an extra-thick, frosty drink, place the cubes in a single layer on a tray and freeze for 1–2 hours before blending.
2. Blend the Base:
   Add the watermelon cubes, ice, and fresh lime juice to your blender. If your watermelon isn’t super sweet, add 1–2 tablespoons of sugar, honey, or agave syrup.
3. Blend Until Slushy:
   Blend on high speed for 30–60 seconds, until the mixture is thick and icy. If needed, pause to stir or push down large chunks. For a thicker slushie, add more ice or frozen watermelon; for a sippable texture, add less.
4. Taste and Adjust:
   Sample a spoonful. Need more tartness? Squeeze in extra lime. Want it sweeter? Add a little more sweetener. For more chill, toss in more ice.
5. Serve Immediately:
   Pour into glasses and garnish with mint, a wedge of lime, or a mini watermelon slice. Slushies are best enjoyed right after blending for peak frosty texture!

Expert Tips for the Best Watermelon Slushie

• Freeze Your Watermelon: For an ultra-thick, almost sorbet-like slushie, use frozen watermelon cubes and skip some of the ice.
• Make Ahead: Prep and freeze watermelon cubes up to a week in advance. Just blend with ice and lime when ready to serve.
• Blender Power: Smaller or lower-powered blenders may struggle with lots of ice; start with less and add slowly.
• No Seedless Watermelon? Use regular watermelon and remove seeds before blending.
• Strain for Smoothness: If you want a super-smooth slushie, strain the blended mix through a fine mesh sieve before adding ice and blending again.

Flavor Variations and Creative Add-Ins

• Strawberry Watermelon Slushie: Add 1 cup frozen strawberries for a juicy berry kick.
• Watermelon Mint Slushie: Toss in 10 fresh mint leaves for a cooling herbal note.
• Tropical Watermelon Slushie: Replace half the ice with frozen pineapple or mango cubes.
• Coconut Watermelon Slushie: Use coconut water instead of regular water or add a splash of coconut milk for a creamy twist.
• Adults-Only: Add 2 ounces of vodka, rum, or tequila for a frozen cocktail—great for summer parties! (Drink responsibly.)
• Watermelon Lemonade Slushie: Add the juice of 1 lemon or ½ cup homemade lemonade for a tart twist.
• Watermelon Slushie Popsicles: Pour the blended mix into popsicle molds and freeze for healthy, fruity ice pops.

Frequently Asked Questions (FAQs)

• Can I make watermelon slushie without a blender?
  Yes! Mash watermelon cubes with a fork or potato masher, stir with crushed ice and sweetener, then freeze in a shallow dish, scraping with a fork every 30 minutes to create a granita-style slushie.
• How long will watermelon slushie last?
  It’s best enjoyed immediately for that frosty, slushy texture. Leftovers can be frozen into popsicle molds or ice cubes and re-blended.
• Is watermelon slushie healthy?
  Absolutely! Watermelon is naturally hydrating, low in calories, and packed with vitamins A and C, plus a boost of antioxidants like lycopene.
• Can I make it sugar-free?
  Definitely—if your watermelon is very sweet, you can skip added sugar. Or use stevia, monkfruit, or another zero-calorie sweetener.
• What can I do with leftover watermelon?
  Freeze cubes for your next batch of slushies, blend into smoothies, or use as garnish for salads and desserts.

How to Batch Prep for Parties

1. Prep Watermelon: Cut and cube enough watermelon for all your guests and keep chilled in the fridge or freeze cubes for thicker results.
