The process of preparing rose beads is a lengthy one, and the recipes for creating them vary by who is doing the creating and whose recipe you use. Some require cooking. Some do not. Some create beads which retain a natural deep red color. Others are turned a shiny, ebony with the use of an uncured, iron pot.
Some recipes even use shortcuts.
In fact, the only common ingredient is rose petals. Gather the Roses on a dry day and chop the petals very finely. Put them in a saucepan and barely cover with water. Heat for about an hour but do not boil. Repeat this process for the three days and if necessary add more water.
