Old timers use rock-salt brines, but they can't compare to the benefits of using Pro-Cure Brine 'n Bite Powder. Brine 'n Bite toughens bait like rock salt and then infuses it with powerful amino acids. This magnifies the smell and flavor of bait and triggers an impulse in fish to feed. It tightens bait scales, and helps keep it fresh longer. Brine 'n Bite produces a tougher bait than the brine method which is critical when fishing anchovies or sardines that are softer than herring.
