Any Raw Steak is received when Butchering dead Animals or by Slicing a Meat Slab. Right-clicking Any Raw Steak and selecting "Slice" will give you 2x Any Raw Meat Cuts. Any Raw Steak can be cooked using the Roasted Meat recipe at a source of Fire such as a lit Fireplace or Pile of Wood. Cooking things over a fire lowers your Insanity a little and has a chance to give you a Gelatinous Lard. Any Raw Steak can be boiled in a Clay Pot or Copper Pot to make Meat Broth.
Any Raw Steak As a Variable Ingredient
When a single type is used as a variable ingredient in recipes Any Raw Steak gives a Restore Bonus based on what animal it was Butchered from.
Meat and Knife Purity
A Knife will take on the Purity of the Bar of Pig Iron used to make its Knife Blade. The Purity of your Knife will transfer directly onto the Meat you receive when Butchering a Creature while your Knife is equipped.
