I've used Colgin in marinades many times for oven jerky but there is a fine line between enough and too much.
I usually use Soy sauce
red wine or a splash of whiskey/rum
brown sugar, about 1/3 to the liquids
garlic/onion powder or chopped garlic/onion
cracked pepper
a few shakes of liquid smoke.
I don't. unless a recipe I am particularly interested in calls for it, then: Liquid Smoke. I just want wood smoke from the smoker for meats... however...
I will confess to adding some liquid smoke to my 'almost nearly world-famous' homemade BBQ sauce...
