Roasting coffee beans at home is easy. However, you will need green beans, an oven, baking paper, a stirring tool, an iron skillet, or a frying pan to get started. The steps to roasting include;

1. Heating the pan

Heat the pan before adding the beans to around 250 degrees Celsius. Do not close the lid so that you can monitor colour change.

Stirring constantly helps to achieve an even roast. You can do it for a minimum of 30 seconds, and after approximately 4 to 7 minutes, your beans will start producing a crackling sound and smoke. Open the window to maintain a good flow of air.
