Liquid smoke is natural smoke flavor captured in water sprayed over burning mesquite or hickory wood. The smoky-flavored water is purified and seasoned with a bit of molasses and vinegar before it is bottled. Look for it near the condiments (mustard, ketchup, barbecue sauce) in the grocery store.
This snack mix tastes just as good at room temperature as it does warm; prepare the recipe in advance and let it cool completely. Seal the mix in an airtight container for up to three days.
Children notice and appreciate cute details: Use fish-shaped cheese crackers to make the snack mix fun.
