Even if you're sick of seeing and hearing about Disney's mega-hit movie "Frozen" everywhere you go, it's hard not to be a fan of these marshmallows produced by Eiwa (¥130) that come in a package with Elsa, Anna and Olaf on the front. Each marshmallow is filled with a tangy yogurt sauce that leaves a slightly sour aftertaste. For a light summer snack, try popping them in the refrigerator or freezer (guess which Elsa would prefer) for a couple of hours to chill the yogurt center. These limited-edition treats will only be around until December, when you'll be forced to "Let it Go."
