Yoshikawa has successfully developed a supreme rust-resistant and durable series of iron frying pans, woks and tamagoyaki omelet pans in COOK PAL REN. Fully seasoned and ready to use after an easy 5 minute process Special Heat Treatment & Rust Resistant Supreme Durability & Toughness Made using nitrided iron without hazardous non-stick coatings. The Cook-Pal Ren is a one-of-a-kind line of woks, manufactured in Niigata, Japan by Yoshikawa Co. No Need for Burning off Coating - Steel Surface is Not Anti-Rust Coated Unlike clear lacquer-finished products, the Cook-Pal Ren's steel surface is not anti-rust coated, eliminating the need for the troublesome process of burning off coating. The wok is ready to use right out of the box. Features of Special High-Temperature Thermal-Treated Steel Plate When the iron surface is strengthened with the special high-temperature thermal treatment, an oxidized layer is formed, which is over five times harder than normal iron. This layer covers the entire surface and penetrates the iron, so no coating peels off when the surface comes into contact with a metal spatula or brush, unlike resin-finished frying pans. Hard to Burn Ingredients and Rust-Resistant The oxidized layer on the steel surface has small holes that allow oil to penetrate, making ingredients harder to burn. The wok is also rust-resistant, making maintenance a breeze. Simply rinse with hot water and wipe with a dry cloth. Extra Steel Content for Intake and High-Flame Cooking Ability The Cook-Pal Ren's iron content discharged during cooking helps fortify your cooking with extra iron, making it a great choice for high-flame cooking. The highly-durable iron allows you to fry ingredients in a short time, creating a crisp texture.
