Adapt it for your goals.
Low-oil
Reduce mustard oil to 1 tbsp total and dry-sear the fish in a non-stick pan before simmering. This cuts fat while keeping the smoky flavour, ideal for lighter eating without losing the Assamese tang.
bone in fishBone-in-fish
Use bone-in rohu or catfish steaks instead of boneless fillets. The bones add body and a subtle sweetness to the broth, making the curry heartier for those who enjoy picking meat off the bone.
smoked tomatoSmoked-tomato
Char one tomato on an open flame until the skin blackens, then chop and add to the gravy. This adds a smoky depth that echoes the mustard oil's intensity, creating a richer, more rustic version.
