The other night at the Red Cross, I took a photo of these sweet potato haupia squares, and it caused such a stir! It tasted even better than it looks, with sweet and rich goodness dissolving in my mouth in every bite. People were demanding to know the recipe.
Well, you’re in luck. The woman who made the dessert, Mrs. Tanaka, agreed to share her recipe. Oh, and if you need a taste tester to let you know if you did it right or not, let me know!
