2, look at the cocoa butter content: chocolate packaging will indicate the cocoa butter content, 80% is considered high content. Of course, the higher the cocoa butter content, the more expensive it is, but it is worthwhile to eat it healthily.
3, look at the ingredients list: the best chocolate is only cocoa butter, sugar and other normal things, do not buy chocolate with nuts or bouquets, that kind of price will not only be expensive but also the things added inside are not pure. Nuts are likely to go bad, and the sugar content of chocolate with nuts will increase a lot. Moreover, more sugar means that it is not pure chocolate, but harmful to the body. It is better to eat nuts alone.
4. Smell it: If good chocolate smells like fragrant cocoa, chocolate, not cocoa butter, will have a pungent taste when it is opened. You'd better smell the chocolate before you buy it. If you think the taste is abnormal, don't buy it.
