What's different about Thai basil?
"So, how does Thai basil stand up against the more familiar Italian sweet basil? At a glance, the most distinguishable difference is the color of the stems: Thai basil has a purple stem and sweet basil has a green stem. And unlike the delicate, floppy leaves you find on sweet basil, Thai basil leaves are much sturdier, meaning they'll hold up better during cooking (sweet basil leaves are usually added fresh, after the rest of the dish has been cooked). Thai basil leaves are also smaller and more narrow than large, circular sweet basil leaves.
But setting looks aside, Thai basil is spicy with an anise, or licorice-like flavor"
