I dont claim to be the authority on curing eggs, but this is the stuff that works for me...... I dont chem cure the eggs that I'm going to use for Steelhead. I cure them in a mixture of salt, suger,borax, and pectin. I do however use chem cures on the eggs I'll be using for Salmon. I like to use pro cure in either the red hot double stuff, or the Steelie pink, and I also like to add a little scent.....Usually the pro cure Slamola powder. I cant give you guys any sort of reason as to why I like to use Chem eggs for salmon and not for Steelhead, It's just a personal preference thing. It's been my experience that Steelhead tend to "eat" the boraxed eggs a bit better than the chem cured eggs, and that salmon tend to prefer the chem cured eggs. Anyhow, just my .02.
