“I believe Rav Solavaitck(don’t know how to spell in English) ate both”

He said that while growing up in Europe, they used lettuce, though he couldn’t say for sure what type of lettuce it was. He said that they also had horseradish, but it seemed from his words that it was because lettuce was rather expensive. He said that he himself (presumably referring to when he was already his own man) used lettuce.
