why dont they melt?

[njbedford]

when using choc chips in cookies, brownies etc, why do they keep their shape and not melt?

[Doggri]

It's a different type of chocolate to usual. They heat and cool the chocolate til it takes on a crystalline structure - and it is harder to melt. Also, the dough of the cookie (or similar) holds the chocolate so it can't really run anywhere. (Most of what I've just written came from the book 'Can Cows Walk Downstairs?', unfortunately not from my own knowledge...)

thank you, kinda guessed the dough not letting it run bit but didnt have a clue about the other stuff, thank you
