Rasam powderRasam spice powder
A spoon of rasam podi, a lime-sized ball of tamarind, a tomato and a ladle of cooked toor dal: that is lunch in countless Tamil homes, from Thanjavur to Tirunelveli, and the podi is what makes one family's rasam taste unlike the neighbour's. This version is peppery and cumin-forward, as rasam should be, with roasted coriander for body and a little toor dal that thickens the broth slightly and gives it a rounded, nutty base. It is meant for clear, thin rasams: tomato rasam, pepper rasam, lemon rasam, and the one you sip as a soup when you have a cold. Make a small batch, since the aroma fades after a couple of months. Common mistake: roasting the coriander seeds until dark brown; they turn bitter and the rasam tastes burnt. Chef's tip: add rasam powder at the end, when the tamarind water is already boiling, and switch off the heat as soon as the rasam froths; boiling it hard kills the pepper aroma.
