After cooking, you can give this dish to the spirit Gustav, as it’s his favorite food. However, this process starts by unlocking and building the cellar, which requires the Master Blueprint Upgrade in Albert’s Shipyard. Aside from that, you will also need to fish for Herring.
Step 1: How To Build the Cellar
As with any task that requires some sort of building in Spiritfarer, the process begins in Albert’s Shipyard, as it’s the only place where the game’s upgrades are available. The shipyard is located in X: 61, Y: 64, just beside Alt Harbor. Additionally, you can also reach Albert’s Shipyard faster via its nearest bus stop, X: 77, Y: 51. After arriving there, proceed to the blueprints section, where you’ll find the Master blueprint upgrade. You’ll find that this is the fifth upgrade, meaning that all four prior upgrades are also required. To help you fast-track the process, here’s a chart of all the upgrade requirements that you need: After getting the Master blueprint upgrade, you’ll unlock the Cellar, along with two other buildings: the Cow Stall and the Smithy. Additionally, the spirit Stanley will also introduce you to the Cellar after he boards the ship. You’ll find it in the “It’s Alive!” request, although you can still build it before then as long as you acquire the blueprint upgrade. As for the building requirements, you will need:
20 Linen Fabrics 3 Comet Rocks 10 Bottled Ectoplasms
Linen fabric is made by using linen thread on the Loom, while comet rocks are collected from the Meteor Showers event that the spirit Giovanni will first introduce to you. Meanwhile, you can get bottled ectoplasm by catching dust shades in the bottled ectoplasm minigame with Jacob, Stanley’s pet beetle. Once you acquire all of the materials, proceed to Stella’s blueprint station and look for the cellar in the production buildings section. If you wish, the game also lets you build more than one cellar. However, like most of the other in-game buildings, doing so doubles the base cost, at least until the fourth copy.
Step 2: How To Catch Herring
Then comes the easy part, which is to catch the only ingredient: herring. Being easily one of the most common fish in the game, herring can be caught from absolutely anywhere on the map. But if you don’t know where to start, then the waters around Alt Harbor at X: 43, Y: 40 is a great starting point. To start fishing, go to the back of Stella’s ship and interact with the seat. Stella will then sit and cast a line into the water. Then, wait until there’s a bite (the bobber will start bouncing) and hold the action button to reel it in. However, keep in mind that you can only reel in the line as long as it’s yellow. Once it turns red, let go of the line and wait for it to become yellow again before reeling once more. Note: reeling at the line while it’s red will cause it to break, while reeling in too late after letting go will release the fish. As such, make sure you time the push and release properly until you eventually capture the fish. Some fish are easier to catch than others, although it can be challenging all the same. Once you get the hang of fishing, just keep doing so until you catch a herring.
Making Surströmming
To make Surströmming, enter the cellar and interact with any of the three compartments. Note that you can place up to five pieces of Herring (or other items) inside these compartments. After putting the herring inside, a timer should appear on top of the compartment you chose, which indicates how long you need to wait for the aging process (fermentation) to finish. This dish should take around 15 minutes to age, and you can do chores around the ship while you wait. Once the timer goes off, a notification will pop up, and you should be able to get Surströmming from the compartment. This dish falls under acquired taste, and you can sell it for 350 Glims. Make sure you don’t take too long in getting the food though, as it will end up becoming a non-edible Expired Meal. If this happens, you have to repeat the entire process.
