About 31 years ago when I moved out of my parents house and was living on my own...
I didn't know very much about cooking or grilling; other than I liked it.
So I learned most things by accident and experience over time. To prevent the meat on
the grill from being burnt I started spraying everything with water from a spray bottle.
It worked great at keeping the flare-ups to a minimum.
One day I thought....Hey; if I
add some flavors into the spray bottle...then maybe the food will taste even better.
So I tried a number of different things to spray on the burgers, steaks, ribs, etc. and
finally came up with something I liked. Others people liked it as well and would turn
down the offer of using BBQ sauce on the meat as It tasted great without any other
sauce on it.
So yes....spraying the meat can absolutely 100% add flavor to whatever meat you are
cooking. I have been doing it with success for over 29 years. Just find the method
you like best....spray or no spray....marinate or no marinade.....low heat or high heat..
...find the method(s) that make your food taste the way you like best and stay
with it. Your taste buds are the only ones that matter.
