food wine gift

Polite gift to take to an Indian lunch?
I’m going to visit my friend from work who is going to show me how to cook some real Indian food – her and her husband are both from India. I would like to take a gift – usually in this situation I would take some wine/beers/flowers.
What would be suitable? I don’t know if she/her husband drinks or not, and it’s a lunchtime.
You can’t go wrong with a nice bouquet of flowers (something unscented like Calla Lillies or Daisies) or a nice potted plant.
