I've jumped off the Kingsford bandwagon after being a loyal consumer for decades. They are pretty much useless now, barely usable in
the Kettle. They are less dense, burn up faster, don't hold heat as long, and give off a huge plume of acrid blue smoke when first firing up. I have 40 lbs left of the previous formula that I am burning up in
the Kettle. I won't buy Kingsford ever again for either
the Kettle or the
WSM.
You've obviously read my Royal Oak Ridge briquettes comparison here in SMF. I now use them exclusively. Here are a few lessons I learned after switching to RO Ridge.
1. They take longer to ash over, about 25% to 50% longer than KBB.
2. After loading my
WSM with Ridge and wood chunks, I fire up only about half as many briquettes in the chimney as I did with the KBB. When I add them to my cold charcoal/wood, my top vent is open, my bottom vents are set at half the level I used to use with KBB. If I'm going to a low temp, bottom vents are completely closed. The smoker comes up to temp more slowly (60-90 mins), but once where I want it, it will stay there for hours and hours.
3. My BBQ Guru used to work constantly when I used KBB. My BBQ Guru has basically become useless since switching to RO Ridge. I now set it 20-25F below my target temp just in case the temp drops. It hasn't yet and I've been using RO Ridge since Memorial Day.
Bottom line, you want a dense briquette, one without a lot of chemicals. Limestone and sand is okay. It helps keep temps steady and holds temps longer. In Ridge that's 10-15% of the weight of the 1 oz briquette (KBB weighs eight tenths of an ounce per briquette).
Some folks say they don't want to pay for limestone in a briquette. I understand completely. I can pick up RO Ridge/Embers/Winco/Kroger (all of them are RO Ridge) for 26-32 cents a pound. Great briquettes like Weber/Trader Joes without the limestone are more in the 60 cents to $1 per pound range. Since I use 400-500 lbs a year, I can't justify the cost difference. Off season, Home Depot Embers (store brand RO Ridge) is the best price available at $4.97 for a 15.4 lb bag, or 32.3 cents a pound.
When you buy lump, buy just one bag, then see what's inside. If you see square pieces that were obviously milled, it is furniture scraps. Avoid those. I only use mesquite lump because no one is making furniture out of mesquite, and thankfully it is easily available here in CA.
I only use lump for poultry. It burns hotter and faster, but RO Ridge holds high temps too. I did two chickens a couple weeks ago and the smoker breezed along at 340-345F without me touching it.
Finding what works for you for taste, cost, and ease of use is a lot of the fun of smoking. I'll use RO Ridge until they start futzing with the formula. Hopefully, they'll avoid the stupidity trail that Kingsford is blazing.
