Recipe Introduction

This bread was created for my culture, the Philippines and Guam, it has deeper meaning for me. The back story is I was born to 1st generation parents. They both went to the US when they were young. When I was born my mother wanted her kids to intergrate smoothly into society. Our culture was set aside, not celebrated. I realised as an adult I am always searching for the food, the parties, the people of my origin. This bread brings me back, it is the essence of my roots. It is core principle number 7-connecting where I came from.
In both countries purple sweet potatoes and coconut are used, they are a great combination.
