Carefully spoon the ground coffee into an empty tea bag. Pull the strings tight to close off the opening, knot to secure.

Wrap the strings around the opening a few times - as shown in the post - and knot once more. This will prevent coffee grounds from floating out of the opening - the initial knot doesn’t close it tight enough.

Once packed and closed, transfer your prepared coffee bags to a Ziplock freezer bag. Press all excess air out and seal; store in a cool dark place until use.

Start your campfire, charcoal, or other heat source. If possible, shift the heat source to one side, leaving the other side as a warm spot. This is a great way to keep the coffee hot when it's done.

In a large pot, boil 10 ounces of water per serving – some will evaporate during heating, and some will be absorbed by the coffee. This will leave about 8 ounces of water per serving.

When the water starts boiling, remove it from the heat or slide it to the warm spot.

When the water stops boiling, add 1 coffee pouch per serving.

Steep for 3 minutes, gently stirring occasionally. If you like stronger coffee, it's better to add more grounds than steep longer. Long steep times can cause it to become quite bitter.

Remove coffee bags and serve.
