You may recall that I have a very small refrigerator. One of the interesting things about such a fridge is that it does not chill consistently from front to back. Consequently, when I set the temperature for my milk to be as cold as I like it, the beverages in the back of the fridge tend to freeze.
I have learned to use this freezing to my benefit: I store a juice drink in the back of the fridge, then when I pull it out I shake it vigorously before pouring*. The result: delicious slushy drink!
*Tip: if you try doing this, make sure the lid is on the juice before shaking vigorously. Otherwise, you will have a slushy mess to clean up in your kitchen, rather than a delicious slushy drink.
