This is actually another sweet I got while staying in my old neighborhood in Tokyo a little white ago. It’s a lightly sweet jelly inside of a bamboo tube. Always love a prop, you can use the plunger to push in through a little grid that slices it into cute jelly noodles. Then you pour a sweet, black sauce over it, similar to molasses. It was a very fun, light snack that I loved, even if it made me nostalgic for my old home!
