Tomato Rasam Recipe with step-by-step pics and a short Youtube video. If you like my video, please do SUBSCRIBE to my channel ‘Asmallbite’. This Kerala Style Rasam is so flavourful, made with freshly ground spices without using any rasam powder. It can be called a medley of our regular Thakkali Rasam or Arachuvita / Mysore Rasam, but there is a secret ingredient hidden in this rasam- shallots (small onion), can you believe it? yes, it lends a very unique taste and aroma to this dish. Also, I like to share some quick tips here, choose deep red, well ripe and country tomatoes for a nice colour and taste, don’t try it with hybrid varieties as the tanginess of the rasam will be missing. It is a must dish in the Kerala Onam Sadhya menu, so if you are preparing on a festive day, do the seasoning in the coconut oil which lends the authentic flavour. Kerala Style Tomato Rasam pairs very well with rice, Kootu Curry, Beans Mezhukupuratti and Nendran Chips.

Notes
Tips for Kerala Style Rasam
- Use deep red and well ripe tomatoes for a nice colour & taste.
- Country tomatoes give more tanginess than hybrid ones.
- Tomatoes can be either chopped and sauteed as I have done, else can be mashed or pureed too.
- Instead of taking tamarind extract, 1 tsp of readymade tamarind puree also can be used.
- Don't skip shallots (small onion) in the grinding part as it is the main and special ingredient here.
- Adjust peppercorns and red chillies as per spice level required for this Kerala Style Rasam.
- Seasoning/Tempering in ghee or coconut oil lends a wonderful aroma. But for the vegan version, do the tempering in oil only.
- Add hing and coriander leaves generously for an excellent flavour.
- Always boil the rasam in low flame, else it loses its flavour.
- Never give more than one boil, otherwise, the rasam taste bitter.
- The ground ingredients settle at the bottom in the rasam, therefore stir every time before use.
- The shelf life of this Tomato Rasam Recipe is 2 days under refrigeration.
