Puto Bigas Recipe
The core ingredient of a traditional puto recipe is rice. You can use all-purpose flour to make it easier if you don't have rice flour. However, if you really want the taste and texture of the traditional version of this steamed rice cake, use rice flour.
If you can't find rice flour, you can prepare the rice in the old-fashioned way: soaked overnight in water and then liquify the softened rice and the water in the blender to start the batter.
