During the trip to Italy, I met Rita Salvadori, a charming chilehead with a great idea.  She manufactures this handy leather pepper powder holder that she calls "Peperita Polveri Peperoncino."  It holds ten vials of pepper powder with heat levels ranging from 1 (Aji Pesce Frutta) to 11 (Naga Morich). The holder folds into a handsome leather case with a zipper that measures 3 x 2.5 x 1 inches, making it convenient for pocket or purse.  I used it to spice up meals both in Italy and London, especially scrambled eggs for breakfast.
Unfortunately, this item is not sold in the United States.  But you can visit Rita's site here, or visit with her on Facebook.  Someone here should license this idea from her—what a perfect gift for the chilehead in your life!
