You heat up the popper on your stove top over a medium/high heat and dump in 10 ounces of green coffee beans. The beans we used were ordered from Sweet Maria’s who carry a wide selection of high-end beans at inexpensive prices.
The only trick with the Whirley-Pop coffee roasting method is adjusting the stove burner. You’re shooting for “first crack,” the point when the beans pop kind of like popcorn. at around the 6 minute mark. Mine took a little bit longer on the first attempt, but after a few roasting sessions I’m sure I’d get the right burner setting. After first crack the beans quiet down for a few minutes. The next thing you’re listening for is the “second crack.” As soon as those beans start making noise again you dump them on a cookie tray to cool down. That’s really all there is to it. Sweet Maria’s has a pdf sheet with more detailed Whirley-Pop instructions as well as a review of other home roasting methods.
Our instructor at the Institute class, Ian Riley, suggested storing the beans at room temperature in a reusable valve bag (freshly roasted coffee beans out-gas CO2).
Unlike many home “artisinal” food methods (we probably need to retire the “a” word), home coffee roasting saves money and you get a much better product than store bought coffee.
Of course quitting coffee would also save money but you’ll have to ask Mrs. Root Simple about that one–I’m an addict.
If you’re in the LA area, you can take Ian Riley’s home coffee roasting class at the Institute for Domestic Technology. I also teach a no-knead bread class at the institute as part of Foodcrafting 101.
