So this is comfort dessert. It is always present at our family gatherings and Holidays. In this recipe we use okinawan sweet potato. The purple color is deep and vibrant, it's beautiful. Haupia is coconut pudding and delicious.
They both compliment each other and the smooth texture is just amazing.
1CRUST: Mix the dry ingredients together in a medium size bowl. Add the chopped nuts and the butter. Cut the mixture with two butter knives, pulling them across each other in a scissor motion until the crust mixture is crumbly and no large butter chunks remain.
2Press the crust mixture onto the bottom of a pie pan, continuing up the sides of the pan. Place the pan in the refrigerator.
3SWEET POTATO LAYER: In a medium bowl, cream the butter and sugar together until smooth and creamy. Add egg one at a time, mixing after adding each egg. Add half of the sweet potatoes, mixing thoroughly. Add the other half and mix again. Mix in the evaporated milk, vanilla and salt.
4Spread the sweet potato mixture into the pie crust, do not add too much, it should fill the pie crust no higher than 1/2 an inch from the top edge of the crust so that we have room for the haupia layer.
5Bake the pie at 350 degrees for 30 minutes or until the edge of the crust is golden and the potato filling is lightly browning in spots.
6HAUPIA LAYER: When the cooked pie has cooled. Begin preparing the haupia layer. You do not want to start preparing the haupia too early or it will solidify.
7Place the coconut milk and the water in a saucepan, but do not turn on the heat just yet. Mix together the sugar and cornstarch in a small bowl then add it to the liquids. Turn the heat on to medium, stirring constantly, until it thickens.
8Immediately pour the haupia mixture over the sweet potato layer and return the pie to the refrigerator to chill for several hours.
