Yudia's Adventurer's Tome is more or less the same as Rethramis's. You have a lot of collectibles to find, and seven of these are cooking collectibles. With not many hints to follow, here's how to get the Natural Mungka Jerky.
Where to find the Natural Mungka Jerky in Lost Ark?
To find the Natural Mungka Jerky, you need to head directly north of the entrance to the Yudia region—Saland Hill—from Rethramis Border, but sadly it's not a straight line. Follow the path west, then head east while keeping close to the southern border.

You'll eventually come across a lone tree next to some Plain Saltbug enemies with a bush below you. These do not harm you or attack you in any way, so you can let them live if you wish. In the bush, you'll find an investigation point, and after a small wait, you will get the Natural Mungka Jerky.
Now all you have to do is open up your Inventory, right-click on the item in question, and it'll automatically be added to your Adventurer's Tome.
