The dessert is a creamy custard filled with raspberry and lemon sauce on top of a cookie.
And it seems you can only find it at Oedo Nursery Cafe that's on Geoje Island.
I was looking for unique desserts to write about today and found this peculiar thing from Korea. At first I thought it was a gelatin dessert because I saw so many today.
I think it looks like a unicorn egg, but would have to be much bigger.

Geoje Island? Is that near Ogygia? I’m also wondering if the suggestion would be a fork or a spoon.
I would ask for both, and then try to figure it out myself.
