I don't do it simply because the color is not to my taste. I would imagine that Helmer has lots of formulas for it.
I used .04 percent sulfur in Jims Regular Batch and .005 percent sugar. I also added .09 percent soda ash. Too little perhaps?
Perhaps Ill try once more at .1 percent before moving on. Volf mentions potassium improving the color. I'll look into Helmer, and salt cake thank you for the suggestion.
