Idiyappam — Rice String Hopper Extrusion Technique (இடியாப்பம்)

Kerala and Tamil Nadu; also central to Sri Lankan cuisine; the technique is shared across the Bay of Bengal culinary region

Idiyappam (string hoppers) are fine noodles of rice flour pressed through a mould with small holes directly onto steaming trays, creating a circular nest of thin rice strands that are steamed until cooked. The technique demands a very specific flour: rice that has been soaked, dried, and finely milled (not commercial rice flour), or a dedicated idiyappam flour. The dough is made with boiling water to partially gelatinise the rice starch, which makes it pliable enough to extrude without cracking. The extrusion pressure must be even and continuous — jerky pressure creates uneven thickness. Idiyappam is a staple in Kerala, Tamil Nadu, and Sri Lanka.

With coconut milk and palm jaggery (sweet), or with prawn moilee or Kerala stew (savoury). Both pairings exploit the bland neutrality of the rice strand.
