Brinjal gothsu (chidambaram brinjal gothsu) is a traditional side dish for idli, with brinjal, small onion, coriander seeds as main ingredients.

You can make anytime of the year when you get fresh brinjals, as side dish for idli or pongal. We make it especially for breakfast or dinner with idli.
Check out my easy side dish for pongal and this idli dosa batter for my soft idli recipe if you want to make.
About
I learnt from my Mom in law, who hails from Chidambaram and they this brinjal gothsu that is very distinct in color and flavor. In addition, very unique I must say!
In fact, this is very famous among our relative and everyone appreciates my MIL. She makes this very often, so she makes it yummiest than anyone.
I initially struggled to get the balance, but now, I can proudly say I too can make very similar to her.

Highlights of this recipe
There's a lot of texture and flavour specifically in this gothsu.
Firstly, the coarse ground brinjal, never ground smooth! Maybe you can mash it too if you like it. My husband, who never eats brinjal likes this gosthu because you can't see it 😃.
Secondly, small onion (shallots/ chinna vengayam) - without small onions, we never make this.
Thirdly, the roasted chilli & coriander seeds powdered and added towards end is the highlight! All you need is this thick, dark and textured gothsu and fluffy soft idli 🙂
Finally, lots of urad dal and chana dal that we add while tempering.
If this doesn't tempts you to try, then you should try once to believe these exact points.😁

Notes
- Note 1: I used small lavender pale purple brinjal for this. But you can use any variety like the vari purple brinjal or plain deep purple brinjal. Some brinjals are naturally bitter so make sure you don't use it. Naatu kathirikai are best 😉 Appoximately 300 - 400 grams. So adjust numbers according to size. If big, use less, if small use more.
- Note 2: The more small onion you add, it is tastier. You can also use large onion but doesn't taste same. Use 2 medium finely chopped onion if using large onion. My small onions measure around 120 gms roughly.
- Note 3: If using solid, you should roast along together. If using powder, add towards end.
- Make sure to cook brinjal completely, otherwise the gothsu will taste bitter.
- Also it is must to add enough tamarind and spice for a good tasting gothsu.
- The gothsu turns thicker as it cools down.
- Drain the water from which brinjal is cooked. Do not use it as it is bitter.

Hi, we make similar pasty brinjal curry and call it 'baingan ka bharta', not exactly same but a bit similar and have it with rice or chaparis/parathas. I will someday make this and try it with doasa and idlis for the first time in my life, thanks for the recipe !

lakshmi says
dressing as well as norms of appearence in urban parts these days is increasingly becoming unisex - it very difficult to figure if cute toddlers are boys or girls 😀
isn't there I'am a stay at home mom option? i think that would be rather cute - although there must be exasperating moments I'm sure its a fun job to take care of your boy :).
RAKS KITCHEN says
Thanx Mona for the comments...:))
Lakshmi,
Yes I agree with your Words:)
I too was searching for home maker option but in vain..
But,as u said ,I love to be a house wife..;D

Looks gud n tastes superb...
Sathya Lakshman says
I made this gothsu. It was so delicious and so simple to make. Usually I make gothsu by roasting the big brinjals on fire. It is tasty but time consuming. This is as tasty yet quick! Thank you so much for this wonderful recipe!
sugu says
Hi, can use big onions instead of small ones? Small onions not easily available in my place..,
Renuka says
We r draining Water from cooked brinjal ..can we use that water to extract tamarind ? Drained water is healthy.
Raks Anand says
I have done that earlier several times but the drained water from brinjal is so bitter. So it spoiled a several times and learnt its because of that water.
