Butter mochi is a beloved dessert here in Hawaii. It is essentially a baked custard. Mochiko sweet rice flour provides its unique, soft, chewy, sticky consistency. As one reviewer noted, it may be a little sweet for some tastes, but I recommend using no less than 2 cups of sugar. I originally put down 375 degrees as the baking temperature because in my gas oven, it saved me 10-15 minutes of baking time and still came out exactly the same way. But most butter mochi recipes will call for 350 degrees. Mochiko flour can be found in the Asian/Oriental aisles. The brand I use comes in a white box with a blue star on the front.
