Hi twoSheds,
It's an excellent question and the answer is really dependant on your preference.
My view is this, a curry should be savoury. Salt goes a long way in achieving this but it is not the only option. I don't add any extra salt to my final dish, preferring to include it in my base and spice mix. I make my base 3000ml at a time and use 1 tbs of salt for that quantity. My spice mix contains just short of 6% salt in it. So, I feel that my end curries have enough salt in them for me to know it's there, but never too much to describe the curry as "salty". I also feel that cooking with salt, allows you to use far less than you would use to achieve the same flavour if you just used it as a seasoning.
To get the savouriness that I desire in my dishes, I like to add fenugreek (Methi). Ground for my base and spice mix, and dried leaf for my end curry.
My suggestion, would be to use salt in your base and spice mix or, to start from scratch. Use no salt, then increase in small increments each time you cook a curry. The only thing with this is, you taste buds can be quite unstable. One day, 1/4 tsp would be plenty, another day, it may not feel like enough, and another day, it may feel far too much.
Good luck,
Ray
