My husband and I enjoyed Puka Dogs with coconut relish while in Kauai, Hawaii. This is my attempt to replicate. It is yummy on hot dogs, brats, or Italian sausage. If you can't find coconut syrup, use simple syrup.
Blend the coconut, jalapeno pepper, Dijon mustard, mayonnaise, coconut flavored syrup, and water in a blender until liquefied; pour into a saucepan and bring to a boil. Cook the coconut mixture at a gentle boil for 10 minutes. Remove from heat and set aside to cool before serving as a condiment for hot dogs.
