Steel, yes I do. But I keep it very little like you, because using much more than that can cause the eggs to milk out into the borax and stay there, so less egg juice to milk out when fishing them; and gooey borax on your eggs when out fishing. Same with sugar. I sometimes put a very small amount of sugar into the borax, but many guys aren't aware that too much sugar can also make eggs milk out. Steelhead do seem to have somewhat of a sweet tooth also, but not as much as salmon do - or I do for that matter. The sugar also acts as a natural color stabilizer. If you want to put more salt and sugar on your steelhead fishing eggs, which is fine if not a big amount, then let them juice out in a container and reabsorb for a couple days in the fridge, as you would do with chem cured 'nook fishing eggs. Then toughen them for fast water use with some air drying time and then borax.
