Technically it doesn't need any salt other than the cure. I don't know it would taste as good. I've been trying to work on low/no salt blends and getting them to taste good is really hard without salt. But from a technical stand point, if you are adding the correct amount of pink salt, then no extra is needed. I try to add more citrus or citric acid when I'm doing a no salt blend. Now I don't do potassium, so I don't have an answer for that question. I just use citric acid or like lemon powder instead of salt.
