Household batteries (the usual suspects: AA, AAA, C, D, 9-volt) can be recycled through battery retailers like Batteries Plus. While you save up enough old batteries to make it worth a disposal trip, keep your dead batteries in a dry place that's out of reach of kids.
Water temperature is vital. Doing it correctly, you can make what many say is the perfect cup of coffee. Ideally, you want the temperature between 195 and 200 degrees F. One way to do this is to boil the water and use an âinstant readâ thermometer from any kitchen store.
Roasting coffee requires skill as well as a proper coffee roaster. A typical roasting temperature ranges from 370 to 540 Â°F (188 to 282 Â°C). Roasting times vary from about 12 to 30 minutes, and the beans shrink about 20% by weight as they gain a dark hue and fragrant aroma. Twenty-five pounds of green coffee beans may take about fifteen minutes to roast.
