Some of the things I take back to France are hot sauces from Mexico, North Carolina, and Louisiana. Don't be fooled by the name Texas Pete — it's an authentic Tarheel product. The largest bottle in the photo below contains Scott's barbecue sauce, made in the town of Goldsboro. It's vinegar, water, salt, peppers, and spices, and it's good on pork or poultry.
I always go to the Mexican grocery while I'm here. I can't find whole allspice berries (pimienta dulce entera) or Mexican oregano (oregano entera, which is actually a kind of verbena) in the American supermarkets — not even in their Latino foods sections. I certainly can't find them in Saint-Aignan. BTW, chipotles are smoked jalapeño peppers.
