I used a cake bundt pan for only parev cakes usually in a fleshig oven I realized that I put the pan which was not used for over a month in a milchig toaster oven, do I need to throw out the cake? Can I keep the pan?
If everything was clean i.e. the pan was clean and was sitting on clean oven/toaster grates, and was baked with only parve, there is no problem with the cake. The pan as well remains ok, but should not be put back in the fleishig oven until 24 hours has passed form the toaster.
