Hey partner. The typical internet recipe that I've come to know is 2 parts trace mineral salt, 1 part stock salt and 1 part dicalcium phosphate (dical). I've heard varying reports on the price of dical lately based on location mostly but it got waaaay overpriced over the last year or more. I stopped adding it unless I find a cheap bag and I also don't add the stock salt anymore because it's not doing much good without the minerals IMO.
So...I'm using plain old trace mineral salt and they hammer it just as well as the mix. Is a single ingredient still considered a recipe?
