I made about a billion runners and riser from a mix of wax and rosin. The smell is so good that this process is addictive. The molten wax is poured on to a granite surface, allowed to cool for a second or two and then mixed with a spatular. Once it takes on a yellow colour it is kneeded in the hand and then rolled like bread sticks on a scraped word surface. Once you have an even and long enough stick it is plunged into cold water to go hard.
