Congratulations. You've simply unlocked a treasure trove of dipping sauces, broths, marinades, and glazes to use in recipes like tuna poke, shoyu ramen, and stir-fried udon. Some rice paper is used for art or writing functions-it’s made out of stuff like paper mulberry or rice straw. Impressively, rice paper doesn’t actually expire, and if saved correctly, it could possibly last indefinitely.
