Fat.
The fats make the chocolate melt quickly. A common fat used in chocolate is cocoa butter.
It depends on how much cocoa fat is in the chocolate; the melting point of cocoa fat is below blood temperature (between 34 and 38oC) so it does melt when you put in your mouth. One side affect of this is that hot countries don't usually have high cocoa fat chocolate for sale as it would melt in the summer.
because of a higher fat content. The Tres bon chocolate you used may also be milk chocolate, which also tends to have more fat thus, melting more rapidly
Although there is no significant difference in the melting points of these two varieties of chocolate, dark chocolate will melt faster than white if you leave both of them out in the sunlight. The dark color is much more absorbent of sunlight.
Yes, because anything with fat melts faster than anything without fat.
no not really
Milk chocolate contains more fat, milk / milk fats / milk solids, and sugar, while dark chocolate contains a higher percentage of cocoa powder in it. The milk and fats are what melt at a lower temperature. Since dark chocolate has more cocoa powder and less fats, it will take longer to melt.
Chocolate is primarily fat (due to the cocoa butter and added vegetable oils in cheap chocolate), however the sugar content determines how much of the chocolate is carbohydrate. Realistically, chocolate will always have a higher fat concentration than carbohydrate concentration, since the less fat it contains, the less it will "melt-in-your-mouth". I.e the more sugar you add, the crunchier it becomes, by which stage it's not really chocolate anymore.
Yes. Milk chocolate is simply dark chocolate with milk and sugar added. Dark chocolate also has many health benefits that milk chocolate does not share, such as fiber and iron. Dark chocolate has significantly less calories than milk chocolate, although there is not a huge difference in grams of fat.
It really depends on the amount of chocolate you are trying to melt.
