What's something you add to (most of) your dishes that gives it a signature taste or a special kick?
I like to throw a pinch of chicken bouillon in a lot of different dishes, sometimes in lieu of salt or in addition to. The bouillon I use also has onion, garlic, and paprika so it gives everything a subtle but welcome kick.
Straight up MSG. If you taste a savory dish and something's missing it's most likely umami. And a pinch of that stuff will add it without any other flavors. Sure, you can also use mushroom powder, nutritional yeast, bouillon cubes or fish sauce, but all those introduce additional flavor notes that I might not want in my dish.
