Nori is a type of edible seaweed that is widely used in Asian cuisine, especially in dishes like sushi rolls and soups. It comes in thin, dark green to black sheets that are often toasted before use. Nori is salty in taste, with a slightly sweet and umami flavor note that enhances the overall taste of various dishes. It's rich in vitamins and minerals, including iodine, iron, and vitamin C. To use nori in recipes, it's typically cut into strips or crumbled into smaller pieces. In addition to being a fundamental ingredient in sushi, it can also be used as a garnish or seasoning for noodle dishes, rice, and salads.

Nori is usually found in the International or Asian food aisle of a grocery store. If the store has a specific section for Japanese or sushi ingredients, you might find Nori there as well.
