Recently I got the resources to furnish my house, and "Garlic Sting, Display" is one of the items that I wanted to add. However, I noticed that TTC has no information about this item. I checked the forums, and it turns out that this is a known issue since at least 2018. When in 2019 the thread got revitalized, claiming that it's still not in the game, it have gotten locked, with a ZOS member claiming that "stuff may have change, start a new thread".
And since it's the middle of 2020, and "Recipe: Garlic String, Display" still doesn't exist in the game, I decided to start this thread, to bring the attention of the developers upon this issue.
