Pro-Cure custom milled borax is a super fine granule so it coats well without caking, and it has an additional 5% moisture added to it so it won’t over dry eggs. Steelheaders seem to prefer boraxed eggs, but borax is also becoming a very important additive when custom curing your eggs with either the Wizard or Pro-Cure egg cure. Try adding a 1/4 cup to a 1/2 cup of white or colored borax to 12 ounces of egg cure. You’ll love the results. Available in 30 ounce reusable plastic bottles.
