Cooking for Blockheads gives you three different recipe books to help you create various Minecraft dishes. The first book is a basic book that only provides the recipes for what is currently in your inventory. You’ll see the available dishes and if you click them then the recipe shows up in the left column.
The next book is a step up from the previous one which will allow you to actually craft the dishes you click. So click once to see the recipe, click twice to craft it.
