Q. Is pasta prepared and packaged by non-Jews permitted?

A. See above question. Avnei Yoshfe (Y.D. 139: 1), quoting Chesed LeAvrohom mentions that if a Gentile cooks food to a point where it is partially edible, but a Jew completes the cooking process according to the Mechaber, it constitutes bishul akum, while the Remo maintains that the partial involvement of the Jew is sufficient to be considered bishul Yisroel.(Y.D. 113; 9). Many kashrus institutions, follow the Ashkenazi tradition of the Remo and permit market available dried pasta since it requires further processing. They also allow non-Jewish companies to prepare specific types of food that cannot be used out of the container without further cooking. Since the final stages will be done by a Jew and the product will then be considered bishul Yisrael. Others maintain that air or heat dried products in principle such as pasta don’t have any bishul prohibition.
Horav Shlomo Miller’s Shlit’a opinion is to be lenient.
