Maple syrup is tree blood. Kind like tree vampirism.
I don’t think wood smells like food. But I wonder… apparently termites have a bunch of gut bacteria to digest wood. Maybe if you eat raw termites and bark beetles, you can then eat some sawdust. If you continue the process eventually you may be able to eat wood or paper with your own gut biome. Maybe start with a termite, sawdust, and banana smoothie and move up from there. Best of luck.
