Catching and Preparing Fish, Clams, and Seafood Dishes
Catching and preparing fish, clams, and seafood dishes starts with a 
Casting Net, the tool used to gather your raw ingredients. Before you can cook anything, you need to craft this net and understand how the rest of the seafood chain fits together, from clams and shell fragments to sliced fish and finished sandwiches.
Crafting the Casting Net
The Casting Net is made with a shaped recipe. You combine 
Shell Fragments with six pieces of 
String. Gather your string first, then secure the shell fragments, since both are required before the net can be assembled.
Getting Shell Fragments from Clams
Shell Fragments come from clams. The recipe is shapeless, meaning the arrangement of ingredients does not matter. Placing a single 
Clam into the crafting grid converts it into Shell Fragments. These fragments then feed directly into the Casting Net recipe, so clams are the starting point for the entire tool.
Cutting Fish into Slices
Once you have fish, several of them can be cut down into slices. Each of these is a cutting conversion:
Bluefish cuts into 
Bluefish Slice.
Herring cuts into 
Herring Slice.
Tuna Chunk cuts into 
Tuna Slice.
Note that tuna behaves differently from the other two. You do not cut a whole tuna directly; the Tuna Chunk is what gets cut into a Tuna Slice. Keep that distinction in mind when sorting your catch.
Making a Tuna Sandwich
The 
Tuna Sandwich has two shapeless recipes, giving you flexibility depending on what you have on hand.
Bread plus 
Cooked Tuna Chunk produces a Tuna Sandwich.- Bread plus Cooked Tuna Chunk plus two cabbage items from the #c:foods/cabbage tag also produces a Tuna Sandwich.
Because both recipes are shapeless, the position of each ingredient in the grid is irrelevant. The second recipe simply adds cabbage on top of the base bread-and-tuna combination. Remember that the tuna must be cooked before it goes into the sandwich.
Putting the Chain Together
The full sequence runs from raw materials to a finished meal. Clams become Shell Fragments, which combine with String to form the Casting Net. Fish you obtain can be cut into slices: Bluefish into Bluefish Slice, Herring into Herring Slice, and Tuna Chunk into Tuna Slice. For a complete dish, cook a Tuna Chunk and combine it with Bread, optionally adding cabbage, to make a Tuna Sandwich.
Quick Reference
- Casting Net: Shell Fragments + six String, shaped.
- Shell Fragments: one Clam, shapeless.
- Bluefish Slice: cut from Bluefish.
- Herring Slice: cut from Herring.
- Tuna Slice: cut from Tuna Chunk.
- Tuna Sandwich: Bread + Cooked Tuna Chunk, shapeless.
- Tuna Sandwich (with cabbage): Bread + Cooked Tuna Chunk + two #c:foods/cabbage, shapeless.
Work through these steps in order: collect clams for fragments, craft the net with string, cut your fish into slices as needed, and cook tuna chunks before assembling sandwiches. Each stage depends on the one before it, so plan your gathering around the recipes you intend to make.
