Sambar Powder vs Sambar Masala vs Rasam Powder

One shelf, three jars, one confusion

Walk into an Indian grocery and you will find sambar powder, sambar masala and rasam powder next to each other. They look alike: brownish-red, fragrant, sold in packets with similar fonts. Brands use the words loosely, and some sell the same product under two names. The mix-up is common, and it leads to sambar that tastes flat or rasam that is far too thick and heavy.

Our library has idli sambar and rasam. This post helps you pick the right jar for each.

The short answer

• Sambar powder is the spice blend for sambar, a lentil and vegetable stew.
• Sambar masala is usually the same thing, sold under a different name. Some brands mean a heavier or darker blend.
• Rasam powder is a different mix, for the thin, peppery, sour soup called rasam. It is usually lighter on coriander and heavier on black pepper and cumin.

If a jar just says "masala" and has no clear dish name, read the ingredient list.

What is usually in each

Home blends vary by family, so these are typical patterns, not rules.

Sambar powder is rounder and a bit sweet from roasted coriander and daal. Rasam powder is sharper and hotter, because the dish is a thin broth and the pepper is the star.

What happens if you swap

Rasam powder in sambar. You get a peppery sambar with less body. Add one extra spoon of cooked, mashed toor daal to compensate and a pinch of coriander powder.

Sambar powder in rasam. The rasam turns heavier and sweeter. To fix it, add 1/2 tsp crushed black pepper and 1/2 tsp roasted cumin at the end.

Curry powder in either. Not a good swap. Curry powder, usually turmeric-heavy, tastes different. Use it only in an emergency, along with extra coriander.

Amounts to start with

For a pot of sambar serving 4, with about 150 g (3/4 cup) cooked toor daal and 300 g (2 cups) mixed vegetables:

Rasam, for 4 bowls: 1 to 1 1/2 tbsp rasam powder, 1 chopped tomato, 2 tbsp tamarind pulp, and a tempering of mustard seeds, curry leaves and dried chilli in ghee. For how tempering works in general, see what is tadka.

Make a small batch yourself

Fresh sambar powder tastes noticeably better than a year-old packet. Dry-roast in a pan on low heat, one at a time, until each smells toasty: 4 tbsp coriander seed, 8 dried red chillies, 1 tbsp chana daal, 1 tsp fenugreek seed, 1 tsp cumin, 1/2 tsp black pepper, 1 tsp turmeric. Cool, grind, store in a jar. Roasting just until fragrant matters because burnt fenugreek turns the whole mix bitter.

Ground spices lose strength with time. How long spices last gives rough guides: use ground blends within about 6 months for best aroma.

Where each one is used

• Sambar powder: sambar for idli, dosa, vada and rice. Also vegetable kuzhambu.
• Rasam powder: rasam, and sometimes poriyal, a dry vegetable dish, for extra pepper.
• Neither: curd rice and lemon rice get their own tempering, not these blends. See lemon rice and curd rice.

If you eat sambar with crispy dosa or idli, the sambar should be slightly thin and quite sour so it cuts through the batter.

Troubleshooting table

Degchi can keep both jars on your pantry list with a note on which dish each belongs to, so you do not buy the wrong one twice; the try-it page shows how items and notes work.
