Place the pepper (capsicum) directly on the flame of your gas stove and turn the flame to high.
Once the side facing the flame is black and blistered, turn the pepper around to face another side to the flame.
Continue turning like this until all sides are black.
Remove the pepper from the flame and place in a bowl and cover tightly with plastic wrap.
If you are doing more than one pepper you can simultaneously do this process on all burners of your stove.
Allow the pepper to sweat in the bowl covered with plastic, approx 1 hour.
Once cool to the touch, remove the pepper from the bowl and peel off all the blackened skin. This can be a bit tedious and you can do this step under running water, but you will have a far better and slightly smokier taste if you avoid running them under water.
Remove and discard the seeds.
Use flesh as desired (learn how to make a simple, but delicious roasted capsicum coulis).
