So I prefer to lightly fry them first.
Ginger & garlic paste,
chopped green chillies,
haldi / turmeric powder,
garam masala powder,
a little oil ( I use mustard oil ),
a pinch of sugar,
salt to taste.
Fry for sometime and then add the ginger/garlic paste. Fry.
This goes to Sudeshna's non-veggie food event.
Updated : If there are some fine bones still left in the mashed fish .... do not worry. When cooking, they are visible prominently ... so you can easily pick them out.
But to be on the safer side ... especially if kids are going to have it ... I would suggest the bigger sized rohu or bhetki's fillet.
