I take a tumbler with an ounce of water and add a teaspoon of salt to it and then add this salty water mix to the curry or dish I am preparing at the moment. I repeat with lesser quantities of salt with each iteration until the dish tastes good. However this approach means adding salt multiple times, before the salt feels right. Not that repetition is bad, but I find people who sprinkle salt either by years of experience or by muscle memory tend to be much better with salt.
What approaches do you follow for adding the perfect amount of salt?
