Directions

  1. In a large saucepan, place a steamer basket over 1 in. of water. Place potatoes in basket. Bring water to a boil. Reduce heat to maintain a simmer; steam, covered, until potatoes are soft, 18-20 minutes. Cool slightly.
  2. Transfer potatoes to a large bowl; mash. Add tapioca, coconut milk, baking powder and salt. Mix until well combined. Transfer to a flat surface. Knead until mixture becomes dough-like, about 2 minutes.
  3. Divide dough by 2 tablespoonfuls. Flatten each slightly and fill with 1 teaspoon of prepared red beans. Cover filling with mochi dough; pinch edges to seal. Roll into a ball.
  4. Preheat air fryer to 360°. In batches, arrange mochi balls in a single layer in greased air-fryer basket. Cook 15 minutes. Let stand for 5-10 minutes before serving.
