Story Behind this Recipe
I wanted to make steamed bread with rice flour, but I wasn't satisfied with the results but they were fine with wheat flour. After trial and error, I came up with a recipe using rice powder (Recipe ID: 1019683) "Gateau au Chocolat Steamed Bread with Rice Flour"
Just cover the lid of the steamer with a towel. When cool, wrap the bread and store at room temperature. These are easy and can be made in about 15 minutes.
