I grilled some bison burgers tonight and used Stubb's Charcoal Briquettes. I've used these briquettes before and have no real complaints. I think it works better for grilling than low and slow bbq cooking. It seems to cook quite a bit hotter than the Royal Oak lump or briquettes that I usually use.
By the way, if you've not visited Stubb's home on the World Wide Web, I'd urge you to check it out. I've seen their products in grocery stores for years, but not really taken time to learn the story behind them. I'm a big Stevie Ray Vaughn fan, so I enjoyed reading about the restaurant "in the beginning". Pretty interesting for sure.
