As fun as fishing, hunting, and cooking can be in Sea of Thieves, one of the most annoying aspects of the game is that despite its size, each ship only has one cooking pan. It takes a bit for your fish to get that nice brown color, and you might have a lot of meat to sell to Hunter’s Call. To ease that pain point, each of the six Sea Forts – added in the Season 6 update – has four burners you can cook on and a Commendation comes with it.
Look under your Pirate Log, Bilge Rats, and Sea Forts to see these awards – the Faster Chef Commendation reads “Cook a meal using all Sea Fort pans at once.” You only have to do this once; This Commendation doesn’t have multiple grades and you can turn this off fairly quickly. All you need is just four fish or chunks of raw animal meat to toss on the stovetop.
When you start a session, check the map on your ship and look for the nearest sea fortress. On the way to the Sea Fortress you can cast out your fishing line and catch some fish to cook later. However, upon arrival you will encounter resistance, either from the Phantoms occupying it or, very rarely, from players who have already forestalled you. Because of this, we recommend keeping any fish you catch along the way in your ship’s bait barrel, as you’ll need your personal inventory space to recover.
Once you’ve defeated a sea fortress, it’s time to cook. If you don’t already have four pieces of meat, it’s pretty easy to get outside and go fishing – or kill some sharks if you’re feeling risky. Better yet, have a full crew of four pirates to fish all at once. When you have enough meat, go back into the sea fortress and turn left; The oven will be on the left side against the wall. Throw fish or raw meat onto all four of these pans – once all four are sizzling at the same time, you’ll earn the Fast Cook achievement.
