Yaki sushi nori is a type of seaweed that is commonly used to make sushi. It has a smooth and shiny side, and a rough and dull side. To tell the difference between the two sides of yaki sushi nori, you can do the following:
Look at the color: The shiny side of the nori is usually darker in color than the rough side. The rough side may appear more green in color.
Feel the texture: The shiny side of the nori is smooth and glossy to the touch, while the rough side is more textured and slightly bumpy.
Observe the direction of the lines: Yaki sushi nori is composed of parallel lines that run the length of the sheet. The lines on the shiny side of the nori are more closely spaced and straighter than the lines on the rough side.
Taste it: If you're still unsure, you can taste a small piece of each side. The shiny side is typically more delicate and crisp, while the rough side can be tougher and chewier.
In general, the shiny side of the yaki sushi nori is used to face down onto the sushi rice, while the rough side is used to face up. This is because the shiny side is more visually appealing, while the rough side can help the rice stick to the nori more effectively.
