Living in Mexico is a good decision for many people. You'll see a statistic that the U.S. embassy in Mexico City estimates that there are more than 1,000,000 Americans living in Mexico and an estimated 500,000 Canadians live in Mexico, at least part-time. That is hogwash used by people who want to sell you something.
Chocolate ice cream is ice cream with natural or artificial chocolate flavoring. Chocolate is the second most common flavor of ice cream in the United States, after vanilla. It can be eaten in a bowl, cup, or cone. It can also be eaten straight from the carton.
From my knowledge the first flavor was the taste of the sweet cream used in the base. Actual flavoring came after the discovery that the cream could be frozen and thickened and retain the sweetness. I would think when ice cream was first made it was just its basic ingredients of cream, sugar and eggs.
