Used it for year's sparky or not, the first time you light up a chimney of this stuff you know by the smell it's great.
A. The only ingredient other than wood is cornstarch.
B. Long, really long burn times, and steady as a rock, the whole low ash thing is no joke amazing for a long low and slow cook.
C. You can go ahead and throw unlit briquets into the cooker with no funky smell or crazy temp spikes.
I swear by the stuff, it has gone through a few cosmetic/manufacturing changes through the years. Last fall I had my local store order me 20 bag's for my winter cooks. They don't stock it in the winter up here in Detroit and instead of the egg shaped briquets I was used to they were square, still nice but strange. Over the weekend went by to grab a few bag's along with some of there organic ketchup which by the way is also great, and the bags I got were back to the egg shaped briquets. Got in the Astro and went back, bought out the stores stock 53 bags worth without a second thought.
Try it if you can, that stinky overpriced blue bag will be history.
