One of the main reasons for the towel is to keep the cutting board moist. As a sushi chef, you want control over the cutting board.
In fact, one of our sushi chefs is religious in how he keeps his towels prepared. He’ll use three side towels, and then and one for moisting the cutting board. Two of the side towels are used for clean hands throughout the shifts, and one of the towels is the backup.
In theory, one towel is all you need. But sometimes, it’s worthy having more towels around while working in a sushi restaurant.
