I want to experiment with a root beer-type flavor, but I don't want to use artificial flavors. From doing research, I know that root beer can be flavored with a number of spices, but the distinctive flavor generally comes from sassafras or sarsaparilla. I am wondering if anyone out there has experience working with either? It seems sassafras specifically needs to be manufactured without safrole to be FDA approved. Now, filé is made from the leaves, but sassafras oil is made from the roots. Is the flavor of the two quite different? Because I see sassafras tea available locally, but I wonder if that would give me the flavor I want or if I should special order the root extract.
