Sometimes the simple things can make an ordinary recipe a “secret” recipe. I’ve discovered one “trick” that adds a special kick to all sorts of sauces and marinades. Liquid Smoke. It is hard to believe they can bottle the stuff… but it’s simply condensed smoke. Made almost like moon shine condensed from the smoke of all sorts of hardwoods but mainly hickory and mesquite. It’s filtered and then sold somewhere between the ketchup and hot sauce.
Just remember it’s strong stuff. A little goes a long way.
