I've got about 2/3s of a package of premade wonton wrappers that I'd purchased in the refrigerator case from the grocery store left over. Questions: (a) Can they be frozen? (b) The label suggests that they can be used to make ravioli. Does anyone recommend this use? I would think that the flavors would be different, but if anyone has had success using wonton wrappers for ravioli I'd be interested. (c) Any other suggested uses or recipes? (I used 1/3 of the package to make the Bittman Shrimp Shu Mei recipe that was in the NYT about 1 month ago. Turned out well but might like to use the rest for something else.) Thanks.
