Every recipe in the game. Put the ingredients in the shape shown, and the finished thing appears in the output square — click it to pick it up.
Press E to open your inventory. The small 2×2 grid is always with you, and it makes anything that fits in a two-by-two square.
Anything taller or wider than 2 needs a table. Make one from 4 oak planks, put it down, then right-click it for the big 3×3 grid.
A recipe can sit anywhere in the grid, and most work mirrored too — a pickaxe is a pickaxe held either way round.
Some things are cooked, not crafted. Put what you want to smelt on top, something that burns underneath, and wait.
Built from the same recipe list the game uses, so it cannot go out of date. Stuck? How to play covers moving, mining and building.
