Cookbook talk:Haupia (Hawaiian Coconut Pudding)

Are the ratios for cornstarch correct here? I'm on my 4th attempt making this recipe and have yet to have anything resembling something that could be cut. Haupia can come in multiple consistencies, including the pudding typing which is what I keep finding with this one. Most other recipes seem to hint at a closer to 1:2 starch:coconut milk ratio for a custard like consistency.
