Again, I have to climb on the Lump Hardwood Charcoal bandwagon. I love the stuff.
You have to shop around to find a good brand. Royal Oak sounds familar. I think I may have used it back in OK.
One thing I do know, is that you have to find a brand with regularly-sized lumps of charcoal. This is why briquettes are so popular, as they burn evenly. I've got a cheap bag of lump charcoal in my garage, and I know it's cheap, with irregularly-sized lumps. Some are huge, most are tiny. This makes laying a fire hard.
There's only two places that I know of right now in my area that sells lump charcoal, a local grocery store, and Lowe's. The brand Lowe's sells is the good stuff. I'll have to go and get a bag or two here soon.
Peace, Love, and Vegetable Rights!
