When summer fruit is at its best, sometimes the simplest desserts are the most enjoyable. These Summer Melon Sorbet Floats combine frozen melon, fruity sorbet, fresh mint and sparkling seltzer in one cold, fizzy treat.
Unlike a traditional ice cream float, this version is lighter and much more fruit-forward. The frozen melon helps keep the drink cold, while the sorbet slowly melts into the seltzer and creates a naturally fruity base.
Another advantage is how easy it is to customize. Watermelon, cantaloupe and honeydew all work, and changing the sorbet can completely change the character of the drink.
What Is a Sorbet Float?
The basic idea comes from the classic float: a frozen dessert is combined with a carbonated drink.
Here, we’re using fruit sorbet instead of ice cream and plain seltzer instead of soda.
As the sorbet begins to melt, it flavors and lightly sweetens the sparkling water. That means you don’t need to make a separate syrup or add extra sugar.
The frozen melon plays two roles: it’s part of the dessert, but it also helps keep everything cold without relying entirely on ordinary ice cubes.
Choosing the Best Melon
You can make these floats with one melon or combine several varieties.
Watermelon gives you a juicy, refreshing flavor and vibrant color. Cantaloupe is sweeter and more aromatic, while honeydew has a milder flavor that works especially well with brighter sorbets such as lemon or raspberry.
Whichever you choose, look for melon that is ripe but still firm.
That’s especially important because we’re going to freeze the melon balls. Overripe, very soft fruit can lose its pleasant texture after freezing.
Why Freeze the Melon?
You could technically make the drink with fresh melon, but freezing it first makes the float much more interesting.
Frozen melon helps chill the drink while adding flavor instead of simply diluting it like ordinary ice.
Give the melon balls at least three hours in the freezer. Spreading them in a single layer also prevents them from freezing into one large clump.
Once frozen, you can divide them between the glasses just before assembling the floats.
Choosing Your Sorbet
This is where you can change the recipe considerably without changing the basic method.
Lemon sorbet creates a brighter, more tart float and pairs particularly well with sweet melon.
Raspberry sorbet gives the drink a stronger berry flavor and striking color.
Other fruit sorbets can work too. Think about the melon you’re using and choose something that either complements or contrasts with it.
There’s no need for every glass to be identical, either. If you’re serving several people, using different sorbets is an easy way to create several variations from the same batch of frozen melon.
Don’t Add the Seltzer Too Early
This recipe takes only a few minutes to assemble, so there’s little reason to prepare the finished glasses in advance.
Add the chilled seltzer just before serving.
Once it meets the sorbet, the frozen dessert begins to melt and the carbonation gradually disappears. That’s exactly what creates the float, but you want that process happening while you’re drinking it—not while the glasses are sitting on the counter.
Pour slowly, too. Carbonated water can foam when it hits the sorbet.
How to Assemble the Best Sorbet Float
Start with the sorbet in the bottom of the glass, followed by the frozen melon and mint.
Then slowly add the seltzer.
Don’t worry if the drink initially looks separated. Give the sorbet a little time to soften. As it melts, it begins flavoring the sparkling water.
You can gently stir it or simply allow the flavors to change as you drink.
That’s actually part of the fun: the last few sips will usually be fruitier and sweeter than the first.
Easy Flavor Combinations
Once you understand the basic formula, there are plenty of combinations to try:
- watermelon + lemon sorbet
- watermelon + raspberry sorbet
- honeydew + lemon sorbet
- cantaloupe + raspberry sorbet
- mixed melon + berry sorbet
Fresh mint works with all of these, but it doesn’t need to dominate the drink. A few leaves per glass are enough to add freshness.
Can You Prepare These Ahead of Time?
Partly.
The melon balls are the perfect make-ahead component. Scoop and freeze them several hours before serving, or prepare them earlier and keep them frozen until needed.
Keep the sorbet frozen and the seltzer refrigerated.
But don’t assemble the actual floats until you’re ready to serve them. That gives you the best combination of frozen melon, firm sorbet and lively carbonation.
Frequently Asked Questions
Do I have to use a melon baller?
No. Small melon cubes work perfectly well. The balls simply make the finished drink more decorative.
Can I use flavored sparkling water?
Yes. An unsweetened fruit-flavored sparkling water can add another layer of flavor. Choose something that works with your melon and sorbet rather than overpowering them.
Can I use ice cream instead of sorbet?
You can, but you’ll get a creamier and heavier float. Sorbet is what gives this particular recipe its light, fruit-focused character.
Do I need to add sugar?
No additional sugar is necessary for the basic recipe. The sorbet provides sweetness as it melts into the seltzer.
Why did my float become flat?
Carbonation naturally decreases after the seltzer is poured, and stirring speeds that process up. Keep everything cold, add the seltzer last and serve immediately.
Can I use fresh melon without freezing it?
Yes, although you’ll lose the extra cooling effect and the distinctive frozen-fruit texture. If you’re short on time, chilled fresh melon is still a workable alternative.
