I prefer lump hardwood
Stubbs briquettes are much better than the blue bag, it has no coal in it. I use lump for almost everything tho.
i've always been a big fan of Walmarts Royal Oak, its made by the same people that make the 'big green egg' brand lump, but much more affordable.
Briquettes are made from sawdust, cornstarch and other nasties.
Are sawdust and cornstarch really nasties? Doesn't bother me.
Despite the difference in smell between briquettes and lump I've never noticed a difference in taste. I don't think most people, if anyone, does.
