Grounds control.

This adorable enamel coffee pot harkens back to a time when making coffee was a simpler affair: just grounds and water, heated up in a pot. We use it as serving piece to bring to the table or a kettle to heat up hot water for tea—but you could also bring the lightweight pot along on a camping excursion to make a quick cup of filterless coffee (just make sure you don't mind a few grounds).
