I prefer the Italian meringue version: it's less prone for breakages (well in my experience anyway). I only colour my macaroons and leave the flavour for the buttercream inside. Just a touch of powdered colours does the trick. You've just got to be really careful, because a little powder can go a long way.... not many people can stomach fluro macaroons. I see some of you wait a few minutes for the mix to dry a little before baking. I've never done that, but I'm curious to see the difference between baking them direct. I bake at 100 celcius (which is 212 fahrenheit for the rest of you), when it's able to lift off the tray you're done. After that I sandwich them together with flavoured buttercream, then pop them in the coolroom for 2-3 days before I sell them.
