hi I'm writing from Israel, I'm Jewish, and I agree that NOTHING in the world beats a good bowl of chicken soup, especially when it's winter and/or you're not feeling well. HOWEVER, I must add a small remark: this recipe is NOT KOSHER.
I don't keep kosher, but I should explain why: any mix of dairy with meat is forbidden for all religious Jews. since the matzo balls in this recipe are made with butter, they are dairy. if you want this recipe to be kosher, substitute the butter with butter-flavored shortening, just make sure it's kosher, and non-dairy. enjoy.
