Question:
Can I use a milchig oven for meat if it's eino ben yomo, I clean the oven well before use and I completely cover the meat with tinfoil?
Answer:
If it is completely covered it will be alright. You have to use a different grate or pan on the bottom of the meat pan, as the taste can go from the rack to the meat.
