Rinsing your salmon before cooking might seem like a good idea, but it can actually do more harm than good. Think about it like trying to wash a dirty car - you're just going to end up spreading the dirt around and making a mess. In the case of salmon, rinsing can actually increase the risk of cross-contamination and spread any bacteria that might be present.
So, what's the alternative? Well, if you don't need to wash your salmon, what do you do instead? For starters, you can give it a quick pat dry with a paper towel to remove any excess moisture. This helps the salmon cook more evenly and prevents it from steaming instead of searing in the pan.
