This is a popular snack in China and Japan. The buns are great right out of the steamer and can also be saved in the fridge for several days and reheated or eaten cool. Extra azuki paste can refrigerated for about a week, frozen, or used as a spread. I got the recipe for the buns themselves from a RecipeZaar recipe by Ms. See. The azuki paste is a modified version of a recipe I found on About.com Prep & Cooking time do not include the time taken to make the azuki paste.
