Payasam is South India's version of kheer — thinner, made with coconut milk and jaggery rather than cow's milk and sugar, fragrant with cardamom and garnished with fried cashews in ghee. It is served at every South Indian festival and as the last course of the Onam sadya. The critical technique difference from North Indian kheer is jaggery — jaggery must be added off heat because its acidic compounds cause coconut milk to curdle at high temperatures.
Cook rice with water on medium heat until very soft and most water is absorbed — 15 minutes. Mash a few grains.
Starting with water rather than coconut milk avoids the protein denaturation that can occur when coconut milk is boiled for extended periods. The rice cooks to full softness in water first — once coconut milk is added, cooking time is minimal.
Add coconut milk to the soft rice. Simmer on medium-low heat for 10 minutes, stirring regularly. Do not boil aggressively.
Coconut milk is an oil-in-water emulsion stabilised by coconut proteins. Aggressive boiling breaks this emulsion — the fat separates and the payasam looks grainy and oily. Gentle simmering maintains the emulsion and produces the characteristic creamy, smooth texture.
Remove from heat. Add grated jaggery and stir until dissolved. Add cardamom and saffron.
Jaggery contains molasses compounds and organic acids. These acids, when combined with the fatty acids in coconut milk at high temperature, cause the emulsion to break — producing a curdled, separated appearance. Adding jaggery off heat prevents this by keeping the temperature below the curdling threshold. This is the single most common error in payasam — adding jaggery while on the heat.
Fry cashews and raisins in ghee until golden. Pour over payasam. Serve warm or at room temperature.
Fried cashews develop Maillard browning at the surface — nutty, roasted flavour compounds that contrast with the sweet, creamy payasam. Raisins puff up as their moisture converts to steam, becoming plump.
