5-Ingredient Fix Contest Entry. I love the flavor combination of potato and coconut and this recipe is so easy! The only thing you need to be careful about is the type of coconut milk you use. The fat content of coconut milk varies greatly among the different brands. Many brands, especially the light ones are simply watered down and if you use them in this recipe, the potatoes will come out watery and will lack flavor. It's best to use Goya or another brand that has about 4-5 grams of fat per ounce.
