What is that special ingredient, "love", with which all ethnic cooks spice their dishes? In this episode I take a sample of cooks along the ethnic spectrum and ask them to define and describe that seemingly intangible ingredient "love" that all ethnic cooks swear by. Ask the question to anyone who is proud of a dish that leaves their kitchen--whether commercial or residential--and most respondents say they prepared something with "love." I'm looking for that love ingredient and just how cooks blend such into the dishes that speak that ingredient.
