First off,
Tele to home and use the fishing teleport ( where many npcs are standing in a line)
When you get there, fish only lobsters
Because its the only working food to cook
Make sure you've caught enough lobs. ( you don't need a lobster pot)
Then tele to ::skill
You'll see a cooking range there ,idk how its called.
Use the lobs on the cooking thing and bam! Gl
