i put hot Mac and cheese into a clean plastic fleishig container which hasn’t been used in a long time (maybe even a year) can I eat the macaroni / can the container be used? Thanks
The macaroni may be eaten, the container should be kashered to be used again with fleishig. This means cleaned, left for 24 hours and dunked in boiling water. If it doesn’t fit in the pot of boiling water, it can be dunked half and then the other half.
