Dear pussy willow-san,
Sorry to be late answering your comment.
Yes, gyo-za is one of my favorite dishes.
I would often cook gyo-za for my daughter and me.
In those days I never bought ready-made gyo-za.
But now I often buy gyo-za at a super market,
since I came to live in Tokyo.
Fortunately I have never bought any frozen gyo-za.
I wonder how the matters will go.
Thank you.
