Lunumiris
Lunumiris ( Sinhala:ලුණු මිරිස් [lunu-miris] Also referred as "Katta Sambal" [Sinhala:කට්ට සම්බෝල [kaṭṭa sambōla]]) is a spicy Sri Lankan sambal paste served as a condiment. It consists of chili pepper, red onions, Maldive fish, sea salt, black pepper and lime juice, usually ground with mortar and pestle or grind stone.
This is a paste which is a little bit hot because of the chili powder added.
