Smoker

A smoker is a butcher's job site block, used to cook food items, similar to a furnace.

Obtaining
The smoker can be obtained by mining with any pickaxe. If mined without a pickaxe, it will drop nothing.

Natural generation
Smokers can generate in butcher houses in villages.

Usage
Smokers cannot be pushed by pistons.

Smoking
Smokers are used to cook food items twice as fast as a regular furnace. When a food item and a fuel is placed into the smoker the block state changes to lit and the item cooks. Fuel is used at double the rate of regular furnaces, so that the amount of items cooked per fuel stays the same. The product can then be collected by pressing on the smoker or by collecting the output using a hopper.

Light source
Smokers emit a light level of 13 when active, just like normal furnaces.

Custom name
By default, the GUI of a smoker is labeled "Smoker", but this name can be customized by naming it in an anvil before placing it, or by changing the  tag using the  command.

Change profession
If a village has a smoker and there is no butcher villager in the village, any villager who didn't already pick a job site block has a chance to change their profession into butcher.‌

Lock
In Java Edition, a smoker can be "locked" by setting its  tag using the  command. If a smoker's  tag is not blank, the smoker cannot be opened unless the player is holding an item with the same name as the   tag's text. For example, to lock a smoker at (0,64,0) so that the smoker cannot be opened unless the player is holding an item named "Smoker Key", use.

Block entity
A smoker has a block entity associated with it that holds additional data about the block.
