Great calculator! However, it has me worried a bit. Based on the recipe I just did for my corned beef (5lbs of meat, 1.5gallons of water, 3tsp of #1, 6.5 wet brine) the recommended amount of #1 was almost double what I put in to get to 200ppm. Also, the curing time was considerable shortly for my 1.5-2" thick brisket flat at 3-5 days. So, what I did was wet brined to 100-125ppm.
I ate it. I haven't died yet. So, is the 100-125ppm ok?
Pedro7,
The goal isn't to reach 200 PPM, 200 PPM is just simply the maximum allowable nitrite. I think the reason 200 PPM was referenced here, was just to show that the other recipe in question was over the maximum limit. I cure most things at about 155 PPM and the beef bacon I make is only 120 PPM. Even cured poultry I keep at 120 PPM....
As long as it was cured, I would say it was fine. You may have used a lower PPM, but you also brined for a longer period of time. Being you did not weigh the meat and weigh the water to calculate the amount of cure, the PPM can only be an estimation. In my opinion it's better to be under the Maximum 200 PPM rather than than over. Obviously you had an ample amount of cure because it was fully cured all the way through. Your estimation of 120 PPM comes out very close to what you had.
We all know that 120 PPM is enough to cure meat, but going down to 100 PPM will be just enough for any meaningful curing action. However the lower 100 PPM could result with inconsistency and you may wind up with uneven curing. Obviously the later was not the case with you..... Congratulations on a great successful curing experience, nothing compares to enjoying the fruits of your labors.
We have discussed why proper weights are more important than estimated measures. Thirdeye even pointed out a link, that measuring spoons can be far from even semi-accurate ballpark measures.
The other point of discussion was, that finding a reliable recipe on the Internet becomes increasingly harder every day. There is a big difference between writing about curing and actually testing the recipe and doing it the proper way. There are many questionable recipes on the internet, just because they are out there, doesn't imply accuracy or safety of the resulting product(s).
From many of these "bad" recipes we can clearly see that the author/poster has never properly calculated the ingredients let alone test the final product. Having a collection of recipes on a website does not make a person proficient in a new skill.
You have to know the How and Why of curing; you have to know the rules that govern the process. The curing agent is simply just a tool, albeit a very important one. Once you understand why and how to properly calculate the ingredients, the rest will fall into place.
Our goal here is only to help educate those who wish to learn; We want you have fun and help to give you a positive experience while making a safe product that everyone can enjoy. We can't force anyone to do something, especially if they are unwilling to learn to do the math. Nothing beats the flavor of a great homemade product, whether it be cured, smoked, or both. No one here is the cure police, we simply want to suggest and help you to find a proven, tested recipe from a true professional in the craft of curing meats. We are only here to offer guidance and suggestions, what the readers do with our input is entirely up to that individual.
However for those who still do not want to weigh for a brine cure, again I advocate the use of Morton Tender Quick as described on the package; 1 Cup Tender Quick for 4 Cups of water. It's not my first choice for a brine cure, but it's based not only on PPM, but also averages a 4% pickup ratio of the brine into the meat.
