Pearl Beach doesn't seem to sell Dan Osmanthus Jelly, but it sells recipes. Moreover, selling groceries's and those selling recipes are still different NPCs, so I suggest you try again.

I suggest you upgrade to 1.06 version. I remember that the later patch update instructions were all about cooking bugs. I forgot the specific content.

As for the materials, some of them need to be obtained by planting osmanthus in Taohua Valley.

Yushan Yangtze River Ferry has. There is a steamed stuffed bun shop there, which can be bought from the boss.

I missed it the first time, too

Then I drove back by myself.

Is the big map open? Talk to all NPCs in Pearl Beach, and they will always be sold! !
