Ingredients
For the rice wafers
- 1 cup sweet rice flour (mochiko)
- 2 tablespoons granulated sugar
- 1/4 teaspoon fine salt
- 1/2 cup cold water
- 1 tablespoon neutral vegetable oil
- 1/2 teaspoon vanilla extract
- 1 tablespoon cornstarch, for dusting
For the smooth red bean filling
- 1 cup dried azuki red beans, rinsed
- 3/4 cup granulated sugar
- 1/4 teaspoon fine salt
- 2 tablespoons water
- 1 teaspoon lemon juice
Directions
- Soak the dried beans in plenty of cold water for at least 6 hours or overnight, then drain. Transfer to a saucepan, cover with 3 inches of fresh water, bring to a boil, reduce heat, and simmer for 35 to 40 minutes until very tender; drain, reserving 2 tablespoons of cooking liquid.
- Mash the warm beans with the reserved liquid, sugar, salt, and lemon juice, stirring over low heat for 8 to 10 minutes until a thick, glossy paste forms that holds its shape when scooped. Cool completely to room temperature.
- Preheat the oven to 325°F (160°C) and line two baking sheets with parchment paper lightly dusted with cornstarch.
- Whisk the sweet rice flour, sugar, and salt in a bowl, then stir in the water, oil, and vanilla until a smooth, pourable batter forms; it should coat the back of a spoon but still drip off slowly.
- Drop tablespoon-sized pools of batter onto the prepared sheets and use the back of a spoon to spread each into a thin, even circle about 3 inches across and roughly 1/16 inch thick, leaving 2 inches between rounds.
- Bake for 12 to 14 minutes until the wafers are pale golden and lift cleanly from the parchment; if any bubbles form, press them flat at the 8-minute mark. Slide the parchment onto a wire rack and let the wafers cool until completely crisp, about 10 minutes.
- Spoon about 2 tablespoons of the cooled bean paste onto the smooth side of one wafer, spreading it nearly to the edge, then cap with a second wafer and press gently so the filling reaches the rim in an even layer.
- Repeat with the remaining wafers and filling, then serve immediately, or store in an airtight container at room temperature for up to 3 days to preserve the snap of the rice shells.
Cook’s Notes
- For an even shorter version, swap the homemade bean paste for 1 cup of prepared smooth red bean paste (koshian) from an Asian market.
- A tortilla press lined with plastic wrap makes quick work of forming uniform wafer discs if you prefer shaping the batter before baking.
- Store finished sandwiches in a single layer in an airtight tin so the wafers stay crisp; humidity is their biggest enemy.
- For a pretty finish, dust the top wafer lightly with powdered sugar or press a thin sheet of edible gold leaf onto the paste before capping.
