I love the smoky flavor of sweet red bean paste and regularly buy the canned Japanese ones but lately I find them overly sweet. I decided to make the paste from scratch mainly to reduce the sugar content. It's not a very difficult process and 2 cups of dried beans make a large batch of sweet paste, about 5 cups, that can fill a lot of pao (steamed buns), baked buns, and hopiang hapon (Japanese-style Filipino-Chinese cakes). I've made the super flaky Filipino Chinese hopia which is a tad complicated and thought making hopiang hapon would be easier because the dough I remember was not as flaky and greasy as the regular hopia, probably closer to moon cake dough.
There aren't many recipes for Filipino hopiang hapon and I adapted the dough from the only one I could find. I underbaked the hopia and they came out pale; and although they don't look like the ones from the Philippines, they taste almost identical. The dough is soft and not sweet at all and I can't stop eating them, they're that good. I'll use a moon cake dough recipe next time I make these.

Sweet Red Bean Paste
2 cups small red beans (azuki)
4 cups water + more to cover
1 cup sugar
2 tablespoons light olive oil
- Clean, rinse, and soak beans overnight in 4 cups water. The next day, drain beans and place in a large non-stick sauce pan; add fresh water to cover and cook over medium heat until tender. Drain, add sugar and oil, and cook over medium-low heat, stirring often until soft and mixture appears dry. For coarse consistency, mash with a potato masher or blend in a blender if fine consistency is preferred. The paste should hold its shape but still moist. Let cool to room temperature, transfer into a container, wrap tightly with plastic wrap and refrigerate until needed.
Hopiang Hapon
dough
1½ cups all-purpose flour
2 tablespoons sugar
pinch of salt
¼ cup cubed cold butter
¼ cup light olive oil
¼ cup water
1 whole egg
filling
1½ x ½-inch sweet red bean paste disks
egg wash
1 egg yolk
1 teaspoon water
- Whisk together flour, sugar, and salt. Cut in cold butter with fingertips. Stir in the rest of the ingredients until combined. Knead lightly just until a smooth dough is formed. Divide into 2 equal pieces and form into logs. Refrigerate for 1 hour. Slice each log into 8 pieces. Flatten each piece into 1/8 inch thick circles. Place a disk on the center and gather the edges. Pinch together and place on a sheet pan, seam side down. Brush with egg wash and bake in a preheated 375°F oven until golden.
Bonus info: The Japanese use ground azuki beans as a facial exfoliating agent. A fellow shopper, a Japanese woman, told me while we were at The Body Shop that her secret to a smooth unblemished facial skin is ground azuki which the store was selling at the time. The grounds came in a tiny box with holes at the top. You wet a small amount on your palm and massage the paste in a circular motion all over your cheeks, forehead, and chin. I used the ground beans on my face for many years but the store discontinued the product. It really works great in removing dead skin making my face smooth as a baby's. I should probably grind some.;-)
