During the summer, when my kids are along for the ride on all of my errands, they ask daily to go to Sonic. Literally daily. So we decided to start trying to make copycat Sonic slushes at home. My favorite Sonic slush has always been the lemon berry, but I really love lime and strawberries together, so we decided to give the Lime Berry Slush a shot. And we’ve loved it–strawberries have been cheap and it’s been fun to make them at home. I will say that despite the fact that I used frozen berries in this picture, use fresh (or thawed) berries. This was an experiment gone horribly wrong. I shouldn’t do recipe experiments when photos are involved.

Questions & Reviews
My kids also beg for Sonic drinks all the time. I had to bring that request to a halt when one child pierced the bottom of the styrofoam cup with a straw. When the cup was full of a red slush. Thanks for a at-home alternative!
This is a perfect way to kick-off our summer when my kids get out next week!
Silly question I’m sure but if sugar is off your food list, along w/all the substitutes, would honey work with this???
I grew up with a Sonic in hometown, but live no where near one now. Strawberry-limeaid slushies are the best! Thanks for this “make your own” recipe, Kate!!
This looks yummy! I really need to get myself a blender.
I’m a bit astounded that your kids have been out of school for a month already, though I spent enough time on the internet to know that school year dates vary greatly!
We have 7 more days for kids, 10 1/2 for teachers! Though as a sub I’m starting to get fewer calls so my summer is gradually beginning.
Yum! It’s our 1st day of summer break. Kids have been up for 2 hrs and I am about to go crazy! This is perfect to bribe my boys with when they get their chores done.
Oh, I need this in my life.
I love the flavor combo here, it looks so good!
Just a tip on the sugar syrup…the homemade stuff will start to grow some mold after a couple of weeks, even if you keep it in the fridge. Even though it sounds CRAZY, I buy bottled sugar syrup at Walmart (it’s with the agave syrup and artificial sweeteners) and it has some citric acid in it to keep the mold away. I can keep it right on the kitchen counter for months with no problem. I use that for my iced coffee, as I don’t use it all that quickly. If I’m doing mixed drinks for a get together, I go ahead and make my own because I know it will get used up. Also, I learned the hard way (at 5:30 AM, no less) that frozen berries AND ice will not a smoothie make.
This lime berry slushy looks scrumptious. I’m not really allowed to go to Sonic anymore because my wife is worried about color additives. Oh well. She’s not really that controlling! Just on food. But these are perfect for the kids after school snack and my get-out-of work snack.
Tom, some of the sugar-free flavors at Sonic are clear. (And sugar-free just refers to the flavorings…the slush base is full of sugar.) Maybe that will help :).
