Lomi salmon (more commonly known as lomi-lomi salmon) is a side dish in Hawaiian cuisine. It is a fresh tomato and salmonsalad, and was introduced to Hawaiians by early western sailors. It is typically prepared by mixing raw salted, diced salmon with tomatoes, sweet gentle Maui onions (or sometimes green onion), and occasionally flakes of hot red chili pepper, or crushed ice. It is always served cold. Other variations include salmon, diced tomato, diced cucumber, and chopped sweet onion.
The name lomi-lomi salmon is taken from the method of preparation. The shredding (dicing) and mixing of the salmon is done by massaging the salted fish with other ingredients by hand (lomi-lomi is Hawaiian for "to massage").
Lomi-lomi salmon is a traditional side dish served at Hawaiian lū‘aus. It is said to complement traditional Hawaiian food consisting of raw diced ahi tuna, poke, kalua pig, laulau, and poi. Lomi-lomi salmon is a classic and integral part of most Hawaiian parties and gatherings, such as traditional luaus, and can be considered a Hawaiian ethnic food.
