Idea of a Food Tree

An "Idea of a Food Tree" is not an item, isn't a tree, and isn't a spell. It's a thought!
In Faunasphere, players could buy an "Idea of a Food Tree" from the first store they see in the game. Teleporting home to their Sphere, an instance of an Idea of a Food Tree can be placed on any Block, regardless of what it was made of.
The Idea looks like a fully grown tree, if that tree was simply a shadow taking up the space the tree should. There isn't actually anything there.
However, a "basic food" item can be placed inside the shadow-like Idea. What is a "basic food"?
A Basic Food item is something that can be eaten on its own as-is, without being creative at all. If that same item is also used as an ingredient in a common dish, with no creativity, then it qualifies as a Basic Food.
Canonically in Faunasphere, meat patties are Basic Foods. So is a cooked sausage, slice of cheese, chili pepper, lettuce leaf, and many others. There is also a Basic Food "Combining Basin", that gets two different Basic Foods and merges them into an Advanced Food. Because every basic food in Faunasphere is able to be eaten on its own or used in the Combining Basin, they can all be grown from Ideas.
Looking to Pokemon for Basic Food examples, there are recipes for Pokeblocks and Poffins. All berries can be used as ingredients in these. However, not all of the berries can be eaten as-is. Cheri Berries are used to cure Paralysis, meaning it is eaten on its own for an effect. Chesto Berries can be held by a pokemon, which will eat the berry on its own... but only if it is put to Sleep in battle. This means that those two berries, and others like it, have both traits- ingredient and consumable. They can be grown from Idea trees. Starf and Enigma berries don't do anything, so they cannot be grown from an Idea.
An Idea of a Food Tree that has been 'fertilized' by a Basic Food immediately changes from the shadow of a fully grown tree into a small sapling that can be physically interacted with as if it was real. The tree grows in approximately fifteen minutes. Every fifteen minutes after this, the Idea of a Food Tree will produce an exact copy, down to temperature, of the Basic Food used. The Idea can produce a maximum of six 'fruits'. Once all the 'fruits' are harvested, the Idea Tree ceases to exist.
In the actual game, I was able to turn one Nola (bamboo sprout-like Basic Food) into six using an Idea of a Food Tree. I harvested them, placed six Ideas, and made 36 Nola. Yes this is exploitable. No, I won't alter this, since it's canonical!
At the same time, Food Tree Ideas can only be created or exist within a Sphere. If a character really wants to have a lot of these, then they need to put effort into their Sphere, so they have enough space for them.
In the attached image, you can see a fully grown Idea of a Food Tree that produces Meat Patties. The green-highlighted one is fully grown and ready to harvest, the other isn't ripe yet.
