A lot of people use a wide varity of premade seasoning salts. I find them a poor way to add flavor to what you are eating, stale and tasting like chemicals. So if you have to use them, make your own. Start with fresh herbs,chili peppers,spices and citrus peels then dry in a low oven around 150-200F, when dry grind in a spice (coffee) grinder and mix with a pure salt like kosher. Store in small air tight jars. Remember things are always going to be better when you make it yourself.
