Looking solely at the picture of the ramen, It looks like the cabbage can only be Napa or Savoy Cabbage. I Never bought Savoy before, so i am going to try steaming it rather then blanching because i dont want to lose any flavor/aroma. Then i am going to dehydrate it. I took a pic of the dried vegetable packet, as you can see, it is mostly cabbage. Did some research, seems Savoy is a popular cabbage used for dehydration. I bought a quart Jar which probably contains more then i will end up from the $4 head i bought from the grocery store. It all good, i bet this Savoy Head is going to make some really good Halupki's.
