Hmmm.... dunno what palak is actually. Saag paneer is a spinach dish (though I think the original greens weren't spinach, spinachhas become standard here).
Palak is always Spinach , Saag can be of any green veggies including Palak (India has variety of spinachs like Fenugreek called as methi, Raddish Leaves called as Mulaa , Gongura called as Ambadi)
Paneer means spinach (or original green variety). The dish is well cooked spinach in ghee and some spices with farmers' cheese (cubes of mild, soft cheese).
Paneer isn't spinach. It means farmers cheese. So Palak Paneer means Cheesy Spinach Curry. Saag is curry of any green vegetable.
Meanwhile love to see Indian foodies....
The most items discussed here are either purely North Indian (Punjabi) and South Indian (idli Dosa Sambhar) which are damn tasty and glamorized in foreign countries.
Apart from this there are few other dishes unexplored from Indian Cuisine
(famous for less spicy and more sweetness... even their curries are spicy in flavor but sweet in taste),
(Persian Moroccan Indian Food),
- Maharashtrian (The costal Maharashtrian cuisine called Malwani is just the same as Thai Food ... damn good),
(famous for fish curries and sweets desserts)
