There are a lot of flavours in common when it comes to Mexican and Indian cuisine. Yes the extensive use of cumin, coriander, chilli and tomato come to mind but there are some lesser known ones like tamarind that feature regularly in both the cuisines. I was fascinated and looked into this and learnt that when the Spanish colonized Mexico, they introduced flavours like tamarind, sesame through the Moorish / African influence.
