Why does salt and seasoning stick better to hot foods?
In every recipe I see for fries, popcorn, churros, and other foods where I normally want to add the salt/sugar/seasoning at the end, everybody says to make sure to do it while the food is still hot so the seasoning sticks. Why is this? Is this just something people say, or does it really matter a lot?

It's really not about temperature at all.
"While it's still hot" is a great description of when to do it, but it's not why.
You want to salt fried food when it's straight from the oil, because the surface is still wet with oil. This ensures that the salt sticks to the surface of the food. As the food sits, the surface will dry (it cools off at the same time-- which is where the "while it's hot" advice comes from).
Even with non-fried foods, heat often comes with surface moisture, either from the cooking process or from the steam being released by the hot food.
Salt sticks to "wet" surfaces. Freshly cooked, still-hot food usually has a "wet" surface (either from water, steam, or oil).

Is it better to add salt before or after cooking?
Adding salt at the beginning of cooking gives it time to migrate into the pieces of food, seasoning them throughout. Meanwhile, if you add salt only at the end, it provides a more concentrated, superficial coating that immediately hits your tongue.Do you put seasoning before or after cooking?
There are different 'camps' when it comes to seasoning but essentially If you season meat too early before cooking, the salt will draw out the moisture, meaning a less juicy piece of meat, however if you season just before cooking the seasoning will help to impart flavour into the meat.What happens when we add salt to food?
It enhances foods by essentially turning up the volume of their salty flavors. Salt can also dial down the taste of bitter foods by suppressing our perception of bitterness, and balance other tastes like sweet and sour (salt added to desserts or vinaigrettes, for example).How can I make my seasoning better for food?
