Personally, I use anchovy paste a lot. It comes in a tube like toothpaste. I never need that many, so it’s nice to not have to open a whole can. It does really dissolve in pasta sauce. I also use it for caesar salad dressing. I think every culture has a way of adding MSG to things, whether it’s pure powdered msg, miso, vegemite, soy sauce, fish sauce, parmesan, mushrooms, or anchovies. For me, it’s really just an msg source with a little extra flavor of its own. I never really use enough that something tastes like anchovy.
