Coffee beans: roasting at home
If you have coffee tree at home, you may experience roasting your own beans in the oven. This will smoke up your house a little, and the smell will stay in the house for quite some time. The quantity and size of beans, as well as your geographical location will bring some correction in the roasting process, so this is a live and learn process.
Place the beans in some perforated container, such as a steel strainer or vegetable steamer. Then place them in a pre-heated, 248,00°F oven for about 5-7 minutes. Then increase the temperature in the oven to 446,00°F. In about ten minutes you will hear the beans to crack. But keep an eye on them, because the time may differ, as it depends on the temperature, heat capacity of the oven, and quality and size of the beans. When the beans start cracking, mix them up, to ensure an equal roast. Look at their color every 1-2 minutes until they have achieved a color a little bit lighter than the final color which you desire.
When the beans have completely cooled, place them in an air tight container in the refrigerator, or just grind them and brew the tasty drink.
