When you cook a stew and it's nasty how do you get rid of it?

You can see the answer here

thanks

Another question, if i built the dam before i got the special algae-eating fish am i doomed?

It's not possible to mess up the game by solving the puzzles in any order you choose.

so how can i get the fish now?

Where are you trying to get the fish from?

i tried to get it from the pond, but then the dam was finished and the pond wasn't there.

Wrong pond. The algae eating fish come from the pond that has the waterfall. To catch the fish has certain pre-requisites. See the puzzle solution guide to find out what type of master is needed and what if any technologies need to be done.

thank u!!! so they come from the lagoon?
