I haven't made coffee over a camp fire in quite awhile. Need to remedy that.
Last time was on the gas stove.
The same kettle as yours but in blue, cups to match.
Crush the beans with the side of a knife blade on stove lid, light stove, water the kettle and put it on to heat. When the water is just about ready to boil add the busted up beans and boil for however long it takes to add wood to the fire or do whatever around camp.
Take the kettle off and slowly pour a cup of cold water in a circle into the pot. That pulls the grains to the bottom. Add Pickeral or Pike to a plate, also matching lol, with some silver dollar fries and enjoy the northern lights lol.
