I have a package of TQ here in front of me and it says 1 cup of cure to 4 cups of water for brine... sugar cure can be used interchangably. Does the sugar cure package have different instructions? Your email from Mortons is what I've always used and what it says on my package of TQ.
No problem... I had to go double check to make sure I hadn't messed up. These proportions are very easy to get mixed up. That's why it's always a good idea to double check your measurements. Happy curing!
