Preheat the oven to 350 degrees. Peel the skin of all the sweet potatoes.
Cut into 1 1/2-in, bite-sized pieces.
Spread the diced potatoes evenly across a large baking dish. Melt the butter in a small pot over medium heat. Add the palm sugar and stir until well blended.
Take the butter and palm sugar mixture off the stove once it starts to bubble. Drizzle it evenly across the potatoes.
Toss the potatoes so that they're evenly coated with the syrup. Bake them in the oven for 60 minutes. Stir them once or twice during the roasting.
Boil the water in a large pot and add the tapioca. Reduce the heat to medium/low, and stir frequently until the pearls are cooked. Approximately 10 minutes, the pearls should become translucent.
Add the coconut milk and salt. Stir well. Let the mixture return to a boil then remove from heat. Remove the potatoes from the oven, you should be able to insert a fork into them easily. Cool.
Spoon a handful of potatoes into a bowl, then pour on the coconut tapioca mixture. Enjoy!
