Onion Chutney - Lipsmacking :)

Not few, there are loooooot of fans for my mom's onion chutney :) Now I am posting this as my friend Madhavi requested the recipe. This is undoubtedly my favourite of all chutneys that mom makes. This can more so be called "Thokku" as its preparation resembles that of 'Thokku' and also this is more spicy unlike usual chutneys and it goes good with rice too.

Ingredients:-
Onion - 2 (Big size)
Red Chilli - 6
Red Chilli powder - 1/2 sp
Jaggery - a small gooseberry size.
Tomato (Opt) - 1/2
Mustard - 1/2 sp
Oil - 3 - 4 Tbsp
Salt

Chop onions (Need not be chopped fine as it is to be grounded anyway)
In little oil, fry the onions for about 5 minutes, add red chillies and fry couple of minutes.
Grind this finely adding salt .
(It is optional to use 1/2 a tomato too , saute slightly and grind along with onions, it adds a bit of tangy taste, but I personally do not like tomatoes interfering in this chutney)
In a hot tava, add 2 spoons of oil, temper mustard and add the grouded paste, red chilli powder and saute.
(Essentially bit of red chilli powder is added to give a good color)
The grounded mixture is to be sauted for about 15 mins minimum, trick and taste to this recipe is being linenant in oil and sauteing for long time, so dont be stingy if you need the taste, add some more oil and keep sauteing until the chutney turns bright brown in color.
Finally add little jaggery, saute couple of minutes, switch off.
This frying is what gives a great taste to the chutney.
Enjoy with any kind of tiffin or with hot rice.
