1. In a bowl, add ground pork, carrot, onion and the ingredient "A" and knead until well combined and sticky.
2. Pour enough oil in a wok or large saucepan and heat on medium-high until hot : Stick in a bamboo chopstick, if bubbles appear, it's hot enough :) Shape the meat mixture into small balls and place in the oil. Cook all sides, turning occasionally, until nicely and evenly golden. Transfer them to a plate lined with paper towels to drain the excess oil.
3. In a skillet, combine all the sauce ingredients and mix them together over a low heat. Place the meatballs and bring it to boil. Once it is boiling, reduce the heat to low, stirring occasionally for about a few minutes. Pour the dissolved katakuriko and mix gently until the sauce is thickened.
