First of all, we apologize for the delayed response. You can get much more immediate support in our Help Center: umaidry.com/help
Second, the UMAi Dry products should contain the proportions that you need for safe curing (relative to weight of meat):
3% kosher salt
0.25% Instacure #2
All you need is a digital scale.
We began providing the Premixed Curing Salts for 5# Recipe because so many customers had trouble weighing and calculating safely accurate proportions. You must use non-iodized salt.
The biggest issue was how many folks want to use volume measurements, but various salts, even various types of kosher salt have significantly different volumes.
Using a digital scale is critical.
Hope this is helpful.
