>"The sodium comes from the traditional Indian spices used in each dish so it's an intricate process to adjust the levels and keep the same quality and taste."
The majority of Indian spices are mostly single element spices - cumin, coriander, fennel, fenugreek, garlic etc.
Even Garam Masala probably the most widely used multi-spice doesn't contain any salt.
Could you elaborate on which "traditional" Indian spices have salt in them?
