Place the apples, pears, raisins, juice, and sea salt in a saucepan. Cover and bring to a boil. Reduce flame to medium-low and simmer three to four minutes until the fruit is tender.
Add the diluted kuzu, stirring constantly until it becomes thick and translucent. Remove from the flame and set aside.
On a heated and dry pancake griddle, place ¼ cup of grated mochi, forming it into a circle like a pancake. Spread one to two tablespoons of the stewed fruit evenly on top of the mochi. Next sprinkle another ¼ cup of grated mochi on top of the fruit.
The bottom layer of the mochi should now be slightly browned and melted. Flip the pancake over and cook on the other side until that side is brown and melted too.
The fruit should now be sandwiched between the two layers of the melted mochi. If this comes out a little messy, don’t worry. It still tastes really good!
