First you want to empty all the yogurt into a bowl. Make sure you have a big enough bowl.
Now you can mix in your food coloring gel. This will get mixed up with the yogurt to give it the blue color.
Now line a baking sheet with some parchment paper and spread the yogurt evenly across the pan.
Now you can sprinkle all the blueberries on top.
Then put in the freezer for about 6 hours or overnight.
Once it's done, you can take it out of the freezer. Now you want to break the pieces up as much as you'd like. I normally use a knife for this because it helps break it apart better.
