To describe the taste of a Galaxy ripple is a difficult task. Obviously it tastes of delicious Galaxy chocolate but if you've never tried any that won't help you much. The taste of Galaxy chocolate is sweeter than other chocolate and more rich and creamy and fantastically cholatey. Some people may find the chocolate too sweet and I certainly know a few people who don't like it at all. The texture of Galaxy chocolate in general is very smooth and it melts quickly and beautifully in the mouth, coating the whole inside of your mouth. Some people may find this texture a little cloying but I love it.
A Galaxy Ripple, (as the name suggests), has ripples. These ripples are similar in effect to a Cadbury's flake but they are more melty, (I'm sorry; I know that isn't a real word), and much less crumbly and flaky.
