See these light roasted beans? They are dull and not dark at all. Booo! This picture is taken with a flash, so you can see that they are really dull or the light from the flash would shine off of the beans!
In preparation for re-roasting your beans, get a cookie sheet and set it beside you. This will be used once you reach the darkness you like. The beans will cool on this cookie sheet.
So, next put the frying pan on the cooktop, turn on the overhead fan, set the heat to med-high and dump the beans in the pan and let it all heat up together.
Get ready to start stirring. Once you start hearing crackling sounds, start stirring. Not just moving the beans around the pan in circles, but I flip them a bit so the tops of the beans as well as the bottoms roast. Keep stirring non-stop! Now this is when it gets a little freaky. Beware that they start smoking.
Seriously smoking. If the overhead fan isn't on.... turn it on now or your smoke detecors will go off. But keep stirring!
They are getting darker and smokier! Keep stirring! Once they reach the darkness you like, remove the pan from the heat and keep stirring. Stir until you dump them onto the cookie sheet and then keep stirring them until they stop smoking.
Here they are on the cookie sheet.
and here is what they look like after they are done. This is taken with a flash, so you can see, they are all nice and shiny and most are black which is how I like them. The oils have surfaced and the coffee is nice and dark. I hope this helps you rescue your lifeless, dull beans!
The end product is soooo much better! Enjoy!
