What are the rules for cooking in a non-kosher kitchen with kosher utensils (pots, cutlery, etc).

  • Can a microwave be used if its contents are double-wrapped?
  • Can the burners on a non-kosher oven be used?
  • Can dishes be washed in a non-kosher sink?

    Welcome to Mi Yodeya! Can you edit your question to make it less personal? We try to avoid practical halachic questions. You might also want to see "Why is it necessary to ask a rabbi?" for more info. We hope to see you around! – MTL Apr 5 '17 at 18:30

    I took the liberty of editing to depersonalise the question. Feel free to further edit yourself. – mevaqesh Apr 5 '17 at 18:32

    You really should ask a rabbi, though. It's generally not a good idea to base real-life practice of halacha on the advice of random people on the internet. – MTL Apr 5 '17 at 20:36

Partial answer from summarizing this OU article:

In both a conventional and microwave oven, double covering the food in foil or plastic is sufficient. (The article explains what the concern is.) A covered hard plastic container is, itself already one layer, so all you need is to cover that in a layer of plastic wrap or foil. An aluminum pan covered with a sheet of foil is all one layer. Then cover that in another layer of foil.

Regarding the stove burners, I am citing an excerpt from another Mi Yodeya answer

After the Return by Rabbis Mordechai Becher and Moshe Newman, a guidebook for baalei t'shuva, covers this

You can cook on a non-kosher stove so long as the burner ring is clean (he doesn't cite a source).
