Vatha Kuzhambu (வத்தகுழம்பு) - Do it youself Video
If you are a graduate student and you have stocked up on some grandma (or mom) made Sambar Powder before embarking on your trip to a non-sambar country (or even managed to purchase some Sambar powder from the stores), you are in luck.
You can make a quick Vatha Kuzhambu using some of this powder, salt, asafoedita(hing) - which is optional, tamarind paste (or tamarind soaked in water). You will also need a pinch of cumin seeds, mustard seeds, some Channa and Toor dal, curry leaves (optional), Appalam (or papad) which is again optional.
The whole thing gets done in under 6 minutes.
NOTE : See how I usually taste the stuff we cook at the end of the video and here we didn't do that? Don't taste this thing as is. Just a touch and lick is fine. Remember, you are creating a concentrate that can be mixed with rice.
One glass of water in this case ends up becoming 1/2 glass (or cup) worth Vatha Kuzhambu. This is enough to mix with 5 cups of cooked rice!!! i.e., it can feed a family of one (aka graduate student) for upto 4 meals!.. Goes great with Potato chips or roasted (microwaved) appalam/papad.
As an option you can also add some frozen shredded coconut to the fried lentils(the Channa and Toor Daal) before you add the liquid in. The upside is it gives you an amazing smell and flavor, but the downside is that it will spoil sooner if you do not refrigerate.
Have fun making வத்தகுழம்பு!
ps. If you know your Appalam is slightly on the salty side, add less salt.. 3/4th spoon of salt for one spoon sambar powder and it will be perfect.
