On the subject of page 115 in the book,
Prawns in sweet and hot curry (prawn Patia)
I think there is an error with the "blending" stage in my book,
it just does not make sense or i read it wrong, so i just use my nogin.
I use the concentrated tamarind from TRS and the jaggery(brown sugar)
i grate into the pan, i store them in the fridge.
Without the sour and sweet agents
this dish gives a very nice standard stir fry dish,
much like a bhona.
If you have not got the green chillies just use a
green bell pepper, i think its the green flesh that gives
it a bit something special.
I have even cooked this outside on my BBQ for friends.
Hope this helps,
graeme.
