1. Make the filling by mixing all the ingredients together. Add the seasonings and mix together until the mixture is sticky.
2. Grab a wrapper and put in your non-dominant hand. Dip one finger in a bowl of water and place it around the border of the wrapper. It should be no more than 1/4 inch.
3. Fold the wrapper in half. Make folds/pleats on each side towards the middle about every 1/4 inch. Press every pleat down hard.
4. Heat a pan over medium-high heat. Add canola oil. When hot, add gyoza flat-side down in a circular shape. Cook until gyoza are brown on the bottom (about 3 minutes).
5. Add ¼ cup of water to the pan. Cover with lid and steam the gyoza until most of the water evaporates.
6. Mix together the ingredients for the dipping.
Remove the lid to allow any other water evaporate. Add the sesame oil. Cook until the bottom is crispy.
