Puttu is a traditional South Indian steamed staple layered with rice flour and fresh coconut. It has a light, crumbly texture with a gentle sweetness and nutty richness throughout.
In a broad mixing bowl, combine 300 g rice flour with salt to taste. Mix in a handful of the 400 g grated coconut and gradually incorporate enough water to form a smooth mixture.
Layer the base of a puttu mould (puttukutti) with a 2.5 cm (1 inch) layer of grated coconut, followed by a 5 cm (2 inch) layer of the prepared rice flour mixture. Alternate these layers until the cylinder is full.
Fit the filled mould onto its water vessel over warm water. Turn the heat to high and steam for 10 minutes until cooked through.
If steaming without a puttu maker, shape the mixture into round portions, arrange them on a plate in a regular steamer, and steam for 10 minutes.
