I keep it thick & add water when I use it for the dressing ( if I feel the need)
Keep thick if you are eating as a dip.
Store it in a glass container, keep the lid bit open/ loose; this will help in keeping it fresh longer.
It has a long shelf life- a month or more, if you keep it refrigerated.
Enjoy it with fritters, samosa, sandwiches, Dahi vada, add in the chat, eat as it is
