If your sister who is not jew cooks food for you thats "clean" can you eat it?

Shalom U'vracha, There are three halachic problems in having your non-Jewish sister cook for you. Only, if all of these problems are solved, you may eat what your sister cooked: 1. You must be sure that the food is kosher. 2. Your sister's pots and dishes are not kosher. You would not be able to eat the food on them unless you first kasher the dishes and pots and silverware (in most cases by dipping them in boiling water). 3. Your sister's cooking is considered בישולי גויים , a Jew may not eat food that a non-Jew cooks. To solve this problem you must participate in the cooking through either of these ways: A. by putting the food in the oven or on the stove. B. by turning on the oven or lighting the fire on the stove. (If the food that your sister made could be eaten without being cooked like carrot soup, since carrots can be eaten without being cooked, then it would also be allowed). all the best
