Sushi, what WOOD you do?

VERY rough mock up ideas.

On receiving the task that i had to come up with a revolutionary food source containing both sushi and wood and create the packaging for the product i was excited and also a bit stumped, but began to come up with a few ideas after looking through my original sketchbooks on both subjects.

I decided on some sort of tree which would grow sushi, but came across a lot of issues and question such as;

Does the tree grow all ingredients needed to make the sushi or does the tree grow the sushi already made?

Am i going to package the seeds or the tree?

Is there one type of tree that grows all sushi's or several different sushi trees?

If the tree grows ingredients then one of the ingredients is going to have to be a type of fish, such as lobster or crab, which belongs in the water and it isn't going to be very safe if a live crab is pincing away on a tree while someone walks by.

I then thought that if i wanted the tree to grow the ingredients then i could think of the fish as just meat rather than a living animal and it could be the equivalent to flowers on a tree and the rice could grow like the leaves of the tree. As sushi contains vinegar rice i then thought that the tree could be watered with a mixture of vinegar and water which would then create the vinegar rice. I then realised that for a tree to be able to grow a substantial amount of sushi the tree would have to be quite large, so i have decided to package the seeds instead of the tree itself.

After thinking i had my food source sorted i decided to look at all the different types of seeds and while doing this research came across tulip tree seeds which are dispersed from pods. This gave me the idea to make a tree which grew pods on it similar to the tulip seed pods, but instead of seeds growing within the pods ready made sushi would grow inside them. The heat from the sun would cook the sushi within the pods and the pods would open on completion of this processing letting people know that they were ready to eat. After the sushi has been picked the pods would fall to the ground becoming the seeds, ready to be planted to create a new sushi tree.

I'm now in the process of coming up with ways to package my seeds so far i've come up with a few ideas but am struggling to come up with anymore, need to do some thinking.
