What is Sashimi?

Sashimi is a Japanese delicacy consisting of very fresh raw meat or fish sliced into thin pieces. Sashimi is often the first course in a formal Japanese meal but it can also be the main course presented with rice mussel soup in separate bowls. Japanese chefs consider Sashimi as one of the finest dishes in Japanese formal dining and recommend that you can eat it before other strongest flavors that can affect the palate.

The sliced seafood that composes the main ingredient is typically draped over the garnish. The typical garnish is Asian white radish,  shredded into long thin strands or single leaves of some herbs. Sashimi is popularly made with a dipping sauce that may be soy sauce with grated ginger.

Sashimi’s Finest Cuts

To highlight the appearance of fresh fish, the chef cuts it by different techniques into different thicknesses. Mostly the slices are cut in a rectangular shape. This is the standard cut of sashimi.
