Is it safe to use a propane torch bought at a Hardware store?
I've come across recipes that involve the use of a Butane or Propane torch. Is it safe to use a propane torch bought at the Hardware store, or is there something different about the torches and/or fuel that is sold at a culinary store?
I don't think that this is a duplicate. The other question does not address food safety concerns specifically.
One very important point to remember if you buy a propane torch from a hardware store is to make sure you buy a "Regulated Nozzle". Otherwise when you tip down to bronze your food it will go off (extinguish).
Propane and butane are pure alkanes. They don't produce anything nasty when burned. The worst you could possibly get should be carbon monoxide (and I am not even sure it can be produced in a torch, the dioxide ifs much more likely), but it being a gas, it won't stick to your food. The complex molecules you get from heating the food itself have more potential for being harmful than the combustion products of a propane butane torch. Ago yes, it is food safe.
Another matter of safety is that it is easier to cause a fire with a hardware store torch, because it has more power than the kitchen ones. But a sensible adult should be able to handle the thing safely.
I agree with the above, just make sure your torch is burning efficiently, i.e. producing a blue flame, not an orange flame, or you may end up with a slightly propane flavored meal.
Might manage to get a little butane monoxide and other such traces, but that's true for the cooking models too.
