Heat up your outdoor charcoal, gas grill, or indoor electric grill.
Using your finger or salt shaker, sprikle salt (kosher or sea salt is better than table salt) on top, bottom, and sides of the skewers.
Spray or brush sake onto your skewers.
Place skewers skin side down on the grill.
After a minute or so, when the side of the chicken starts cooking hot, it'll start sweating out chicken juices. Tat the point, flip it over so the hot juices stay on the chicken. This makes sure you get juicy yakitori. Keep flipping every minute and cook the sides as well.
When the yakitori looks golden on all sides, it's almost done. Dip your yakitori in the tare (or brush it on) and put it back on the grill.
Caramelize the top and bottom for 30-45 seconds each on the grill.
Plate and serve immediately.
