I buy the 3.1 lb bag (Kingsford how about just 3.0 lbs) anyhow I put the whole bag into the bottom add a couple pounds regular charcoal, creating my 2 zone fire. Then sit back wait 15-30 minutes depending on weather. Result the best BBQ, and a perfect end to a perfect steak.
I love this stuff, it lights quickly and ready too cook fast. Don't waste money on the cheap store brand stuff you will be disappointed. Stick with Kingsford!
