This isn't really an item within the game, but rather a food, so I'll add a 2nd post for it in specifics. (I will add more favourite foods/dishes to this post when I can find more)
Anyway - unfortunately I was not able to do the flash/mini (5 day) goal at the time because I was under level.
However, I'm glad that since I've build the "Headstone Oven" even after the goal has ended, I still get 1 of the newer recipes unlocked for free.
The Nightmare Cake.
It pairs really well with my Black/green area.
It's definitely one my newer favourite recipes that have recently came into the game.
Here is a picture of it combined!
Though to be fair, I'd wished for it to be a decoration rather than a recipe, so I'm not having to cook it as much, or accidentally mix up counters in the process, but it's still very cool.
When the other recipes go and sell, I will definitely add it to my corner again!
