Morton® Tender Quick® mix is a fast cure product that has been developed as a cure for meat, poultry, game, salmon, shad, and sablefish. It is a combination of high grade salt and other quality curing ingredients that can be used for both dry and sweet pickle curing. Morton® Tender Quick® mix contains salt, the main preserving agent; sugar, both sodium nitrate and sodium nitrite, curing agents that also contribute to development of color and flavor; and propylene glycol to keep the mixture uniform. It is NOT a meat tenderizer.
Morton® Sugar Cure® (Plain) mix is formulated for dry or sweet pickle curing of meat, poultry, game, salmon, shad and sablefish. It is primarily used for dry curing hams and bacon. It contains salt, sugar, propylene glycol, sodium nitrate and sodium nitrite, a blend of natural spices and dextrose (corn sugar). Morton® Sugar Cure® (Plain) mix can be used interchangeably with Morton® Tender Quick® mix.
Morton® Smoke Flavored Sugar Cure® mix is formulated especially for dry curing large cuts of meat like hams or bacon. It contains salt, sugar, sodium nitrate, propylene glycol, caramel color, natural hickory smoke flavor, a blend of natural spices and dextrose (corn sugar). The cure reaction takes longer with Morton® Smoke Flavored Sugar Cure® mix than with plain Morton® Sugar Cure® mix, so the smoke flavored product should be used only for dry curing and not for making a brine (pickle) solution.
