How do you unlock and craft the iron cooking station?

Unlocking and crafting the Iron Cooking Station in Valheim is a mid-to-late game progression step that significantly improves your food preparation capabilities. This station allows you to cook more advanced recipes, which are essential for surviving tougher biomes like the Swamp and Mountains. To unlock and craft the Iron Cooking Station, you must first progress through the game''s tech tree, gather specific resources, and defeat certain enemies.\n\nTo begin, you need to acquire Iron, which is found in the Swamp biome. Iron is obtained by mining Muddy Scrap Piles in Sunken Crypts, which are dungeon-like structures scattered throughout the Swamp. Before entering the Swamp, ensure you have a Bronze Pickaxe, as it is required to mine Muddy Scrap Piles. Additionally, prepare for the Swamp''s hostile environment by crafting Poison Resistance Mead, which protects you from the deadly Blob and Leech enemies.\n\nOnce you have gathered Muddy Scrap Piles, return to your base and smelt them in a Smelter to produce Iron Bars. You will need 10 Iron Bars to craft the Iron Cooking Station. However, before you can craft it, you must unlock the recipe. The recipe is unlocked by obtaining a Surtling Core, which is dropped by Surtlings found in the Swamp or in the Ashlands biome. Surtling Cores are also used to craft Portals and Smelters, so prioritize gathering them early in your playthrough.\n\nAfter unlocking the recipe, you can craft the Iron Cooking Station at a Forge. The Forge is a crafting station that requires 6 Copper, 4 Wood, 4 Coal, and 10 Stone to build. Place the Forge in your base and ensure it is fueled with Coal. Once the Forge is ready, open the crafting menu and select the Iron Cooking Station. Crafting it requires 10 Iron Bars, 4 Wood, and 2 Surtling Cores. Place the Iron Cooking Station near your other cooking stations for convenience.\n\nOne common challenge players face is surviving the Swamp biome while gathering Iron. To overcome this, always bring a shield to block attacks from Draugr and Skeletons, and use a Mace or Club, as these weapons deal extra damage to Swamp enemies. Additionally, build a small outpost near the Swamp to store resources and rest, as this reduces the risk of losing progress if you die.\n\nThe Iron Cooking Station unlocks advanced recipes like Sausages, which require Entrails, Raw Meat, and Thistle. These recipes provide higher health and stamina bonuses, making them essential for tackling tougher biomes. To maximize efficiency, always keep a steady supply of ingredients and fuel for your cooking stations.\n\nIn summary, unlocking and crafting the Iron Cooking Station requires progression through the Swamp biome, gathering Iron and Surtling Cores, and building a Forge. Prepare thoroughly for the Swamp''s dangers, and prioritize gathering resources efficiently. With the Iron Cooking Station, you can cook advanced recipes that will greatly enhance your survival in Valheim''s challenging world.
