The word “thattukada” brings me a lot of good memories. Am sure that every Malayalee has tried this local fast food version at least once. The thattukada is a road side eatery / fast food outlet / hawker food. If you've been to Kerala, you can't help but notice these thattukadas where porottas are made and I should say that sight itself is kinda appetizing!
My brother is a thattukada fan and he is the one who introduced me to this world of fiery n colorful thattu specials. He used to get parcels for me. His thattu favorites were squid curry, fried rice, kappa n meen curry and beef curry.
He had the habit of checking the dinner menu at home and if he was not happy, he'd immediately take his bike n go n fetch some thattukada specials. I used to wait to see the expression on his face to decide whether I should start having dinner or wait for those fiery thattu specials ;)
I guess spiciness is the trademark of thattu dishes and this curry is no exception. Please adjust the masala measurements to suite your spice tolerance level.
