Instant noodles, or instant ramen, is a type of food consisting of noodles sold in a precooked and dried block with flavoring powder and/or seasoning oil. The dried noodle block was originally created by flash-frying cooked noodles, and this is still the main method used in Asian countries; air-dried noodle blocks are favored in Western countries. Dried noodle blocks are designed to be cooked or soaked in boiling water before eating. Ramen, a Japanese adaptation of Chinese noodle soup, is sometimes used as a descriptor for instant noodle flavors by some Japanese manufacturers. It has become synonymous in the United States with all instant noodle products.
