When we visited Totsukawa, we picked up a yubeshi. A hollowed out yuzu (citron) that is filled with savories like katsuobushi, sesame seeds, miso.
One way that we were served the yubeshi was thinly sliced on top of cheese, so that is one way that we had it at home.
Good with beer.
Another way that was suggested was as chazuke (with tea and rice).
So we tried it this way as well.
I like the yuzu flavor in the tea.
I froze most of this and will take it out every so often for us to have as pupu (appetizer) with cheese.
