I know what "for one thing" means. But sometimes idioms are used in such a way that gives non-native speakers a hard time to understand their meaning.
I encountered the following passage:
She had never cared for the kind of tea on offer in her hometown, but in the two weeks she had spent in Assam she had developed an unexpected affinity for the tea on offer here. There were no spices in it for one thing, and this was more to her taste than the tea at home.
I guess the last sentence means "Her hometown's tea had no spices whereas the tea available in Assam has spices. And that is the one reason she likes Assam tea over her hometown's tea." Am I right? Please correct me if I'm wrong.
