We love Dale's. The main ingredient is soy sauce, which explains the salt.
Steve, was your Old Bay old? (I know... old Bay old... heh) We've used Old Bay for decades. When it gets old, it seems to turn to extra salty.
The label on Tony Chachere's says to use it like salt, and when t's salty enough, the other spices will be at the right level. Same with Slap Your Momma. My son likes it, but I'm not a big fan.
