Besides the obvious propane and charcoal

I found a can of sterno on the shelf while shopping and got me thinking.

Side question have you cooked with sterno cans? Id assume you could just hard to control the heat without many tests.

Your reviews would be greatly appreciated.

Which kerosine burner are you running?

I have the little Coleman single burner propane that I bought very recently. Super-portable and hot, but I cooked bacon and sausages for a Cub Scout den meeting in a cast iron pan and it felt too top heavy. I did it in the church parking lot, so it was on asphalt and a stable base. My mother-in-law found a case of 1# coleman bottles at a yard sale, in various stages of fill.

I have my parents' ancient Coleman camp stove that runs on white gas. Built like a tank, but fussy to light. That may be due to it being 50 years old. I have a gallon can of white gas that never manages to pour without spilling. I fill one of the MSR bottles from that so I don't have to clean up every time I fill.

I've got a Weber little smokey with charcoal briquettes that I keep handy for cookouts at the park and I have a big ceramic grill with a bunch of good lump charcoal for Good Eats.

I try to keep a cord of firewood on hand, but I don't have a dedicated fire pit for cooking. You can build a fire anywhere, though, and I have a Lodge dutch oven. I'm either going to build an easy sunken hearth or buy a steel fire pit.

My wood stove won't quite boil water even it is cranked way up. I've tried to make tea on it. I suppose I could simmer pasta sauce or chili on it.

I have one of these . These stoves are in use everywhere in the rest of the world. You can get them for less money not on Amazon. Asian markets also sell the fuel by the case. I also have a Coleman stove and a grille as well as a wood stove in the house. I have seen old Sterno that looked like it had dried up. I have a few cans of it as well but it is not my go to.

I checked that one out. Gas One is a popular manufacturer and it is $20-30 on Amazon. It runs in butane. There is a more expensive model that will run on butane or propane. Nifty!.

Besides the electric range, white gas canister or liquid stoves, Esbit/trioxane bars, and I'm going to get a solar oven eventually.

I have some sterno cans around along with some of the chaffing dish things.  The chaffing dish things are more a fire starter or to keep things warm.  Sterno cans are ancient but I doubt it goes bad.

Propane is easy.  Even if you just have a propane grill outside you can break out the cast iron stuff to cook on it.  A dutch oven will work if it fits and a frying pan always works it seems.

Dutch oven for outside stuff, amazon was clearing out some of the tri-pod sticks for hanging a dutch oven or coffee pot over a fire so I got a couple of those just cause.  With the outside dutch oven it should have a lip to help hold coals on the lid but you can do all sorts of things with just what you have available.

Got a wood stove?  Can cook off its flat top if it has enough room.

If it is summer then yeah I could see playing outside and maybe making some sort of home made fire stove thing out of some coffee cans or something. 

Heck, people are using plain ol cinder blocks to do stuff outside, pinterest is infectious.

I also stocked up on some of the trioxane or whatever esbit bars are and have a few of those little things around. 

Propane cooktop can be rigged up for camping use if you don't buy an actual camping setup.  I have an old 3 burner setup from a small apartment stove and it is just built into a drawer to give it something to sit in and protect the underneath.

Coleman stoves, both coleman fuel type and propane type, are all over these days.  Find some used or barely used and needing cleaned up and mess with em.

I do have some decently thick cookwear other than cast iron, I prefer something sturdy and all of it would work for use outside if needed.  But some stuff is made better than other stuff.

If it is winter and the tower heaters using kerosene are being used just putting a pot of water on it can heat up a stew, I messed with it in the past but it varies on how well I think you could cook on it.  These days with a handheld temp gun I would be more willing to mess with stuff I guess.

Dual Fuel Coleman stoves, charcoal grill, I have 20 lb propane tanks and a stove also have a grill hooked up to a 500 gal buried propane tank. I have a Lodge tri-pod to cook with if it comes to that. Generator and electric skillet also.

Solar

Besides propane there is the Fireplace and fire pit outdoors.

Disposable grills
Propane grill
Propane single burner (camping)

Sterno
Alcohol stoves

A note about sterno, it doesn't really get hot enough to "cook" stuff, and takes a long time to do anything. You aren't going to boil water for mac n cheese with it.  You can use it to heat beans or whatever.  When I use sterno, it's a secondary heater that goes along with the primary cooking tool. 

Cast iron 2 burner propane stove. I can run it on my 5 gallon bottles or off the 330 gallon buried tank. I keep charcoal on hand. I do need to start stacking some dried oak wood. I do have 2 water sources, city and well water.

Thanks for the replies will respond if any questions.
