Question:
Is a green apple considered a dvar charif?
More specifically, we have an apple slicer/corer that my kids use on all sorts of surfaces (not necessarily dairy; sometimes just the top of a random table that i'm not sure of the kashrus of) and recently used it with a green apple on a dairy cutting board. Is there a problem with my cutting board?
Answer:
Hello,
Your cutting board is still kosher. Firstly, we have no substantial reason to say that the apple corer is not kosher. Even if it was, b’dieved we are not machmir that the cutting board got the taste inside the apple corer.
