The process

Heat (don't burn - be carefull) the fat in a pan. Stir in ashes. Pour the broth into some moulds/molds and let sit. That's about it. The quantities of the ingredients depend on the quality of the fat or the ashes. Just try - won't be that difficult.

Add fragrance by putting lavender, roses or similar into the mixture.
