Store in the freezer. Unless you’re eating these just hours after making them, they’ll need to thaw. Set out on the counter for a minimum of 30-60 minutes to soften, or thaw in the fridge to desired texture. I like them best super soft with no iciness.
You can also keep these in the refrigerator instead, for more of a soft cream pie type of dessert, if you like.
Double the crust if you want to make these into sandwiches. Yum!
If you can find wild Maine blueberries, use them!! The flavor is *amazing*. Depending on your berries, you may need a little extra sweetener if they are more tart. Just taste and adjust before you freeze your ice cream.
