This Jerusalem Post story probably contains much more than you ever wanted to know about the wonderful and mysterious etrog (also known as the not-so-mysterious citron, whose candied peel is commonly found in fruitcake). But it's a wonderful piece that contains nuggets of fascinating information on, for instance, the contribution of Jewish religious rituals to agricultural, economic and gastronomic developments in relatively far flung parts of the world, as well as in Eretz Yisrael.
Enjoy! (And since I neglected to say so earlier this week, Happy Succot!)
Shabbat Shalom.
