My relative is going to Tijuana shortly. She offered to bring some things back for me. Any must have recomedations? I am going to ask her to bring back some of the mexican tuna cans. I also like some of the pottery serving pieces such as the ones in the Williams-Sonoma catologue to serve salsa, and guacomole, and other mexican dishes. I was warned that much of the mexican pottery has lead. Is there anything to look out for to assure you are not getting lead glazed pottery?Also, how about mexican vanilla, how does it compare to the one at Williams-Sonoma. Any other recs. greatly appreciated.
