Let us make Tar from raw meat in the kiln or fireplace

Later in the game, we get a low of raw lower-tier meat we never use. This is still useful as tar, except you need to make it at the fireplace by holding down click for each piece.

The kiln lets us make Tar directly from wood and dirt, the fireplace only lets us make the cooked versions of raw food.

Also, please let us continue cooking cooked food in the fireplace to turn it into Tar - this currently isn't possible, so if you release click too early, oops you're stuck with lower tier food you'll never use.
