We coming to Mazatlan in June for 2 weeks and bringing my son, who is a very picky eater. Can someone tell me if any of the local grocery stores sell Malt-o-Meal (we usually shop at Gigante but are willing to shop around in this case)? If not, we will have to bring some. Can I bring an unopened package of it through customs? And if I can, will it slow us way down by forcing us to go through the agriculture line and have our bags gone through? Also, we've had vanilla in Mexico and while the grown-ups like it, it does taste different and my son doesn't like it. Do stores carry vanilla from other places (Madagascar, India, etc)? And again, if not, can I bring an unopened bottle through customs? I'm happy to say, he loves Mexican food, but not for breakfast.
