How about something like an Indian Spice Set? That way, he can experiment and make his own curry at home. You could include some of his favorite spices such as cumin, turmeric, coriander, and garam masala. Alternatively, you could find a local Indian restaurant that offers cooking classes or workshops where he can learn how to prepare curry and other traditional Indian dishes. This not only shows him that you're interested in his interests but also offers him an opportunity to learn something new and spend time with you. Additionally, you could consider gifting a set of Indian recipe books or a cookbook authored by an Indian chef.
Or you can get him a star map with an important date you share.
