Daifuku (Sweet Filled Mochi)

Introduction

Daifuku is a soft, pillowy mochi ball wrapped around sweet bean paste—it takes about 30 minutes total and requires just five basic ingredients. The magic happens when you microwave the glutinous rice flour into a stretchy dough, then wrap it around marble-sized balls of anko filling while the mochi is still warm and pliable.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 15 minutes
• Total Time: 30 minutes
• Servings: 12

Ingredients

• Anko filling
• ~½ cup potato starch (katakuriko)
• 1 cup sweet glutinous rice flour (mochiko)
• ⅔ cup water
• ¼ cup white granulated sugar

Instructions

1. Prepare anko filling as directed. Shape into 12 small, marble-sized balls and set aside.
2. Prepare a smooth surface, such as a cutting board, by coating with potato starch; be generous, as the dough will be very sticky.
3. Heat water and sugar together in a microwave until sugar is dissolved. Add rice flour and stir completely. Microwave for 2 minutes, remove and stir. Microwave for 2 more minutes, or until dough begins to expand. Remove from microwave, stir again, and remove the dough to the potato starch-coated surface. The dough, called mochi, will be very hot.
4. Spread or roll the mochi dough out until thin. Using a knife, cut into 12 even sized pieces.
5. Coat the palms and fingers of your hands in potato starch. Spread each piece out as thin as possible.
6. Place an anko ball in the middle of each mochi piece, then wrap the mochi around the ball, forming a bigger ball.
7. Roll shaped daifuku in potato starch, and set on a plate dusted with potato starch or a piece of wax paper.
8. Serve warm or cool. Store in an airtight container. Very perishable.

Variations

Different fillings: Try matcha-sweetened cream, fresh fruit purées (strawberry or mango), or sweetened chestnut paste instead of anko. The wrapping technique stays the same; only the filling flavor changes.

Dusting alternatives: Instead of potato starch, dust finished daifuku with cornstarch or a mix of cornstarch and powdered sugar for a slightly sweeter exterior.

Smaller portions: Make 18 to 20 mini daifuku by dividing the dough and filling proportionally. They work well as petit fours and cook in the same time.

Chilled serving: Refrigerate finished daifuku for 1 to 2 hours before serving. The mochi firms up slightly and becomes easier to handle, though the texture is less tender than warm daifuku.

Tips for Success

Work quickly with the mochi: Once removed from the microwave, the dough cools and stiffens fast. Coat your hands generously with potato starch and stretch each piece thin while it is still warm; cold mochi will crack or tear.

Use enough starch: The dough is extremely sticky by design. Coat your work surface, hands, and the outside of each finished ball liberally with potato starch to prevent sticking and make handling easier.

Check for even pieces: When cutting the mochi into 12 pieces, aim for similar sizes so each daifuku wraps evenly around its filling without gaps or overhang.

Prepare anko in advance: Make or buy your anko filling and let it cool completely before shaping into balls. Warm filling will soften the mochi and make wrapping difficult.

Storage and Reheating

FAQ

Can I make the anko filling myself, or should I buy it?

You can make it by simmering dried adzuki beans with sugar until soft and smooth, but store-bought anko is convenient and reliable. Look for it in the Asian foods section of your grocery store or online.

Why does my mochi crack when I try to stretch it?

The dough has cooled too much. Work faster and keep your hands well-coated with potato starch. If it hardens, you can briefly microwave the whole batch for 20 to 30 seconds to soften it again.

How do I prevent the daifuku from sticking to the plate during storage?

Dust the storage plate or container base generously with potato starch or place a piece of parchment paper between layers. The starch prevents the daifuku from fusing to the surface.

Can I eat daifuku if it becomes hard after a day?

Yes, but the texture will be less tender. You can soften it as described in the Storage section, or eat it as-is—it will still taste good, just firmer and slightly chewier.
