Chicken breast wrapped in perilla 鶏胸肉の青じそ巻き

This is inspired by a recipe in one of the food blogs I follow. I have previously posted yakitori 焼き鳥 dishes made with a combination of chicken meat, perilla and "umeboshi" 梅干し salted plum paste (this is a classic combination). One such dish used chicken tenderloin  another used chicken made into a roll with shiso and umeboshi paste, cut into medallions and skewered. This is the same combination of flavors with some different twists.   I cut the chicken into bite sized pieces, pound the pieces to break down the fibers, and marinate them before making the skewers as the recipe suggested. This preparation really made the chicken breast much more moist and tender. (My wife asked if this was sous vide chicken breast). I served the pieces un-skewered and instead of adding plum paste in the marinade as suggested in the recipe I put it on the top which has a more direct impact.

Ingredients (For the three skewers seen here):
One half of boneless and skinless chicken breast, cut into bite sized pieces, pounded with a meat mallet to break down the fibers.
Perilla leaves (We have a forest of perilla in our herb garden, 4 feet tall!)
Light olive oil for cooking.

For marinade
2 tbs sake
1tbs light colored soy sauce
1 tsp potato starch (katakuri-ko)

Directions:
I placed the chicken in a Ziplock bag with the marinade ingredients. I kneaded the bag to mix the meat and the marinade. I removed the air as much as I could before closing the bag. I refrigerated it for a few hours.
I cut the perilla leaves to the width of the meat and long enough that it wrapped the meat all the way around (some of our perilla leaves were quite large and had to cut them into several pieces). I wrapped the chicken pieces and put them on a skewer. (Althouhg I cooked the chicken in a frying pan rather than over charcoal, it was much easier to flip the skewers and keep the perilla leaves on the meat) (#1).
I added a small amount of light olive oil to a non-stick frying pan on low flame (#2), Put on the lid and cooked it for several minutes and then turned them over (#3). I used an instant thermometer to make sure it read 165F and the chicken was done before taking the skewers off the heat.  (#4).

I was going to use a tube of salted plum paste but it was near-empty and looked old. So, I made plum sauce or "Bainiku" 梅肉 sauce from "umeboshi" 梅干し salted plums (my mother's last batch sent to us a few years ago) (#5). I removed the meat from the stones and chopped it finely and put it in a Japanese "suribachi" すり鉢 mortar (#6). I gradually added mirin みりん until the ground plum became a thick saucy consistency. I smeared the sauce over the chicken (the first picture).

Although this is a variation of a "golden" combination of chicken meat, perilla, and salted plum sauce, this variation was really good because of the tender and moist texture of the chicken.
