So I threw away a little bowl I found at the beginning of lvl 1. I saw a video that show someone making something in that bowl though so now I wonder if I made a mistake in throwing it away and if there will be another one at some point? Im doing quest for the Dwarves at the moment...
Don't worry about tossing that first bowl. You will find a number of bowls during your explorations, and they all do the same things.
Bowls serve two potential purposes: 1) they can act as a container (similar to a sack or backpack) that can only hold food, and 2) a bowl (any bowl) is needed to make Rotworm stew. Once a particular bowl is used to make stew, it can no longer function as a container.
