I've learned through experience you can cook almost anything in the Helios, as long as you're careful with the fuel throttle and keep your food stirred constantly. My favorite use, however, is first thing in the morning for that first cup of coffee. I've found that by using the GSI collapsible cone filter support, a #4 paper cone and an insulated jug I get a perfect a quart of coffee in less than 10 minutes with easy cleanup. It's as good as the drip coffeemaker at home.
