Bring 75 ml sake (pour the other half of the sake in a glass), mirin, soy sauce, sugar and ginger syrup in a pan to a boil and let it simmer fora bout 5 mins on low heat. Stir regurarly. Pour 1 or 2 big spoons of this sauce in a small and deep baking tray and set the rest of the sauce aside.

Put a piece of chicken and a piece of spring onion on a skewer. Finish the skewer by adding three more pieces of chicken and two more pieces of spring onion to it. Repeat this for the other skewers. While making the yakitori skewers, drink the sake that you’ve put in the glass.

Preheat a grilling pan and meanwhile marinate the skewers in the sauce you put in the baking tray. Put the marinated skewers in the hot grilling pan and turn them every minute. Before turning brush them with some of the sauce from the baking tray. Keep turning and brushing until the chicken is cooked and the skerwers are nice and brown (should take 4 to 6 minutes).

Serve with plain rice, noodles or as a snack. Sprinkle some fried onions over the yakitori and serve with some sauce you kept in the pan.
