Using charcoal starter is the simplest and easiest way to start charcoal. Put charcoal inside the charcoal starter and heat it up on the gas stove.
We have charcoal starter easy to use at home and a larger durable type to use in professional kitchen too.
Charcoals can be easily extinguished by using charcoal extinguisher. By putting the lit charcoal inside the pot and sealing it, charcoal would gradually extinguish due to lack of oxygen. The extinguished charcoal can be reused and easily start fire.
If you extinguish charcoal inside water, you would need to completely dry the charcoal to reuse it.
