There is a known story of how one time a person brought a giant carrot on Erev Pesach to the Belzer Rebbe (back in Europe) for Karpas. After the donor left, he said "burn it with the Chometz". As the donor came home, his non-Jewish maid told him that she saw that he wanted this carrot to be a special carrot for his Rebbe. To help, she decided to water it with beer.
The farmer ran back and told the Rebbe what happened. The Chassidim were amazed at this miraculous occurrence, but the Rebbe answered "It was no miracle. It's just that we don't use carrots for karpas".
I have two questions:
- Is there a halacha prohibiting one from eating a food on pesach whose entire growth was from Chometz? (Or was it a Chumra?)
- Does this rule apply throughout the year (is one permitted to eat a carrot that grew on blood, for example)?
