Tomato ketchup has too many to companies in competition, namely Kissan, Surabhi, Smith and Jones, Tasty Treat etc. Now I personally love the taste of Kissan in all of them. But, Kissan, being a sub-brand of Unilever is not Indian and plus I think its a bit pricey.
The cheapest of all ketchup packs in the market is theTasty Treat which is available in only select few areas. Surabhi was nice too but it almost vanished from all stores. Now only Kissan and Smith and Jones can be seen, with Kissan being awesome with its spicy sour taste which can bring any bland snack to life as well as enriching the taste of an already tasty snack.
