Question:
I boiled rice in a dairy pot and left it in the pot overnight. If I wanted to make fried rice the next night using a parve saute pan (putting the cooled rice from the dairy pot into the parve pan & reheating it), would the parve pan remain so? How does nat-bar-nat work here?
Answer:
It the permitted, because it is a double secondary taste, ( nat bar nat bar nat), it will not make the pot dairy.
