ACK! Why are you putting chemicals in your food??
Believe it or not, liquid smoke is all natural. Smoke from wood chips is passed through a condenser, turning it into a liquid. Liquid smoke is a great and easy way to add smokiness to your food when cooking outside simply isn't an option.
OK, so where do I find this stuff?
You can find it at most grocery stores. It's usually in the same aisle as marinades and barbecue sauce.
