I used the rocksalt recipe this last year and was quite successful. Of course, I think that anything, even bare hooks, worked this year.

We plug cut the herring while still a bit frozen, cleaned out the guts, rinsed, then added about 1/2 gallon of water to a 1 gallon jug and dropped in a cup of either rock slat or canning salt.

I always cut my bait the evening before.

Never tried the bluing, powdered milk, or borax cause mine seemed to work just fine. Maybe I'll try it this year.

280 salmon to the boat this year, so they must have liked something about the bait.
