How do you use a percolator camping coffee pot?
Put the amount of water desired into the pot, put the desired amount of grounds (a tablespoon per cup) in the basket, place the percolator shaft into the basket and position the assembly in the bottom of the percolator. place the lid on the basket and the lid onto the percolator and place the percolator onto your heat source (campfire or stove). when the water begins to boil allow it to percolate for 3 to 5 minutes (depending on your taste preference), then carefully pour the coffee into a cup.
This is not the best way to treat coffee, but it allows you to enjoy the ‘old way’ of making coffee. It produces a great aroma, but the coffee can be a bit ‘stout’….
