Recently I came across this Masala flavored Popcorn by Swad having the spices of red chili powder, which might be a good alternative, though I have not tried it.
Taste of home is the main instinct factor for most of chefs!
Masala Popcorn gives a great kick to the flavor of popcorn, For the really high spice lovers, some finely chopped jalapeño will coat the popcorn well. Low fat tasty alternative to the buttery popcorn, and also possible to have more, as its not so high in calories! I had two servings and enjoyed the fennel, cumin , green chillies and curry flavor in the popcorn. Masala Popcorn while watching movie, made the movie more enjoyable and memorable!
