• Cooking Okinawan Sweet Potatoes (from cooks.com): Please note that the potato size may affect cooking times and that the purple will turn brownish when exposed to air. BAKE: Poke some holes in it with fork. Bake in 400 degree oven for 30-60 minutes until it tests soft when pierced with a fork. STEAM: Poke a few holes in washed potato. Steam 30-45 minutes until tender. MICROWAVE: Cut in half lengthwise. Put the cut side down in 1/2-1 inch of water. Microwave on high 5-7 minutes. I've also seen a suggestion to start it off with a few minutes of microwaving before wrapping in foil and baking in the oven.

Steps:

• CRUST: 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.
• Press the crust mixture onto the bottom of a pie pan, continuing up the sides of the pan. Place the pan in the refrigerator.
• SWEET 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.
• Spread 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.
• Bake 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.
• HAUPIA 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.
• Place 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.
• Immediately pour the haupia mixture over the sweet potato layer and return the pie to the refrigerator to chill for several hours.
