Keep in mind that most mass produced chocolate here in Argentina is VERY low quality in terms of its ingredients. Good quality chocolate has a high cocoa content which in turn contains cocoa butter. Here most chocolate has almost ALL of it's cocoa butter removed (which is the chocolate's naturally occurring fat) and replaced with hydrogenated oil. When most or all of this fat is removed the name chocolate is replaced with "baño de repostería" which in effect means "confectioner's glaze" in English. Take a look at any of those really cheap chocolate bars - and read the ingredients or you will see this phrase directly on the wrapper. If you are concerned about quality ingredients (and your health for that matter) avoid "baño de repostería" when it comes to chocolate in Argentina. The brand "Aguila" from Arcor is probably your best bet in terms of any quality chocolate for a reasonable price. It comes in either a pink and white or black wrapper. The "Aguila" brand has both real chocolate which comes in bar / tablet form AND "baño de repostería" which comes in a pouch and I am going to guess that their chocolate chips are probably made out of this stuff too, so make sure you read the label, if it's important to you, of course.
