I'm sure that most of you do this already, but for those who don't, maybe this tip will help!
The next time you are about to salt a pot of food, precede the addition of salt with some other spice that will show up clearly in the food. For example, if I'm adding salt to a pot of Venn Pongal, I'll add ground black pepper first, then the salt. This way, when I stir up the pot thoroughly, and mix the pepper through, the salt gets mixed at the same time. I know that everything is blended through perfectly when I see that the pepper is evenly blended. I do this, because there are times when I'll salt something, and end up with little pockets of salt. It's decidedly unpleasant. This technique helps me ensure that everything is evenly blended.
