Ingredients

Instructions

  1. Step 1: Boil 400 g peeled Okinawan sweet potatoes in a pot of boiling water for 15-20 minutes until very tender, then drain and mash until smooth.
  2. Step 2: In a mixing bowl, combine the mashed sweet potatoes with 1/4 cup all-purpose flour, 1 large beaten egg, 2 finely chopped scallions, 2 tbsp toasted sesame seeds, and 1/2 tsp salt; mix well to form a slightly sticky batter.
  3. Step 3: Heat 3 tbsp vegetable oil in a large nonstick skillet over medium heat until hot but not smoking.
  4. Step 4: Scoop 1/4 cup portions of the batter into the skillet, flattening each gently with a spatula to form 3-inch diameter cakes.
  5. Step 5: Cook the cakes for 4-5 minutes on each side until golden brown and crisp on the edges, then transfer to a paper towel-lined plate to drain excess oil before serving warm.
