Instructions

1. In a sauce pan, heat coconut milk (do not boil). Mix sugar, salt, and cornstarch with water; stir into hot coconut milk. Cook, stirring constantly, until mixture thickens (cook over low heat to avoid curdling). Stir in vanilla and cool.
2. NOTE: It is best to chill the haupia until it is somewhat thick, but still spreadable; otherwise it kind of goops up when you try to spread it on the layers.
