Minecraft: How to make a Smoker
(Read time is about 1 minutes)
4 Wood Log (Any type) + 1 Furnace --> Smoker
This 1.15+ Minecraft item acts just like a Furnace... except the Smoker can cook food items 2 times fast. (But the catch... only food)
See Blast Furnace or Furnace for ones that can cook other than food.
