<human>:  How do I roast coffee beans?
<bot>: To roast coffee beans, you will need some kind of heating source, such as an oven, a pan, or a specialized coffee roaster. Begin by preheating the heating source to the desired temperature, usually between 356-480°F (180-249°C). Then, place the beans in the heating source and stir or agitate the beans periodically to ensure an even roast. Monitor the color and aroma of the beans to determine when they are finished roasting. It is usually between 5-15 minutes, depending on the desired taste. Once finished, remove the beans from the heat source and allow them to cool before storing them.
