Step-by-Step: How to Make This Raspberry Lemonade Slushie for a Crowd
Do the work once. Serve it all afternoon.
Step 1: Make the Simple Syrup
Combine ¾ cup sugar and 2 cups water in a small saucepan over medium heat. Stir until the sugar fully dissolves — about 3–4 minutes. Pull it off the heat and let it cool completely.
👉 Make this the night before. It keeps in the fridge for up to two weeks.
Step 2: Blend the Raspberries
Add 4 cups of raspberries to the blender with ½ cup of water. Blend until smooth — about 30 seconds.
Strain through a fine mesh strainer into a large bowl. Press the pulp with a spoon to get every drop of juice. Toss the seeds.
Step 3: Mix the Lemonade Base
In your large pitcher, combine:
- Raspberry purée
- Fresh lemon juice (1½ cups)
- Cooled simple syrup
- Remaining water to taste
Stir it well. Taste it. Adjust the sweetness or tartness now — before the ice goes in.
Step 4: Add the Ice and Blend in Batches
Here's where it becomes a slushie. Work in batches:
- Add 2 cups of the lemonade base to the blender.
- Add 2–3 cups of crushed ice.
- Blend until smooth and slushy.
- Pour into the serving pitcher or dispenser.
- Repeat until done.
Straight up — crushed ice blends faster and smoother than cubed. Worth the extra step if your freezer doesn't crush automatically.
Step 5: Serve and Garnish
Pour into cups over extra ice. Garnish with:
- 🍋 A lemon wheel on the rim
- 🫐 A few fresh raspberries on top
- 🥤 A colorful paper straw
Add lemon-lime soda at serving time if you want a little fizz. Pour it in gently so it doesn't flatten.
