salt (something) with (something)
1. To season an item of food with some kind of salt or something in place of salt. They salt the meat with coarse sea salt, then grill it very quickly on each side. They say that Napoleon's chief surgeon salted horse meat with gunpowder to feed to the soldiers.
2. By extension, to make something more interesting, dynamic, or lively by the addition of something else. Why they felt the need to salt the original story with all these huge CGI action scenes is beyond me. You've packed a lot of great information into your presentation, but try to salt it with some humor or interesting anecdotes. It's just a bit dry as it is.
3. To make something appear more valuable by adding or applying something to it in a fraudulent or deceptive manner. Beware when buying a second-hand car. Some people will salt a lemon with a fresh coat of paint and try to charge you the cost of a newer, better car. They used to simply weigh the bags of produce without checking the contents first, until they realized that some of the workers were salting their bags with stones.
4. To apply a layer of random data to a password or pass phrase in order to further encrypt it. It turns out that the retailer wasn't salting its users' passwords with any kind of randomized data, which made them vulnerable to hackers. Because most people use simple, easy-to-crack passwords, our system salts those with elaborate data packets to make even the simplest password impossible to access.
