Bests & Worsts Reviews from Amazon

I just got this book and I am frustrated with it for 2 reasons. It's a one project book (and I knew that when I ordered it) to learn how to make striped meringue kisses. That involves three things--making the meringue, piping the kisses with colored stripes and baking them. I am a pretty confident baker but I wasn't sure how to color the meringues, specifically what food coloring to use. As meringue is really sensitive to liquids and oils I didn't know intuitively what food coloring product to use and I didn't feel like going through a bunch of trial and error so I did the lazy thing and bought the book. In the whole book the only thing said about food coloring is this: "Using natural food coloring...". That's the only time it's mentioned. In my house I have liquid, gel, paste and air brush food coloring. The book doesn't tell me which products will work and which ones won't and it doesn't tell me why the authors use natural food coloring. Is it a preference of the authors or will my meringues absolutely deflate if I use a commercial product? I have no more information than I did before I bought the book. The second reason I am frustrated is the interactive content. There are 9 or 10 interactive videos referenced in the text. Maybe there is more information in the interactive content but it is only accessible through an app called Layar and I don't have a smartphone. The book lists no other way to access the videos. If I wanted to buy a smartphone with an app called Layar on it I would have ordered that but I ordered a book. Please give me more than one way to access your interactive content. So frustrating.
