Do you eat food that is homemade when you are by a kiddush – when A) You don’t know from who’s house it came from (cleanliness). B) You don’t know the status of the kashrus in the house that it was made in?
I can’t remember the last time that that’s happened (i.e. that there was homemade food at a kiddush AND I didn’t know from where it came).
