Swedish Fire Log aka Swedish Fire Torch aka Canadian Candle

[UTC-10]

An ersatz and expendable form of fire barrel.  Because it is consumed by the fire, it would not be permanent.  The use of a section of log would probably make it somewhat not casually portable.  It can make use of crafted line from gut (crafted line does not burn in this instance) in its crafting.  A hatchet or hacksaw would be needed to craft. 

How long it would last, would depend on implementation decisions as  it might have a specific time limit i.e., 2 hours then it goes out regardless since the log was consumed or it might be a one-time use for a maximum of one or two hours.  Harvesting of the Canadian Candle could yield one piece of wood or a few sticks plus some charcoal (dev implementation decision).  

The base stock would be obtained by deciding whether the character wants a Log or Pieces of Wood from a tree limb.  For limbs that yield 3 pieces the character can obtain one log in lieu of those pieces.  For larger limbs that yield 5 pieces, the character can obtain two logs in lieu of those pieces.  

Crafting

The Canadian Candle is crafted by splitting the log into 4 or 8 pieces, clearing out an interior cavity, cutting a vent hole in the side, then reassembling the pieces, tied together with crafted line, which the end (making assertion that it would be smooth enough)  then serves as a platform for cooking, water making, with the body of the log serving as fuel and a wind shield.  It has one nominal cooking surface that requires a pot to use though there might be accessories like a grill to substitute for it.  Recycled cans (two) can be placed on the top beside the fire hold and will melt snow at 2 the normal duration.  

Whether the Canadian Candle can be extinguished and moved to another location then relit is a dev implementation decision.  

Game implementation matters and I may be reaching about what it can do but it did look interesting in this video on Kent Survival channel on youtube  Swedish Torches - 3 styles of 1 log fire .
