FOR EVERYONE ASKING ABOUT DYNAMITE, THE DESERT. YOU NEED THE DESERT. IT'S SAND CLAY AND GUNPOWDER. you get those by combining mucus and sand for Sand Clay, and you get gunpowder from fire plant and powershroom.
I had the recipe for a while so I don't remember, I'm doing a rerun to try and figure that out. if I do i'll respond again or edit this comment to add it.
I hope my suggestion will help,if you didn't have the recipe for making dynamite and didn't know where to find it (just like what I have experienced), then you can try to do the quest that give you dynamite repeatedly. this method works for me
