There are liquorice flavour, mandarin orange, caramel, white chocolate, pistachio, lemon, hazel nut, raspberry, lychee etc. The choices are endless to your imagination even champagne flavour. There are also salty savoury flavour macaron for example macaron au foie gras.
I am somebody who needs to visualized a recipe instead of reading a recipe. So I have illustrate a recipe for dummies just for myself and of course to share with anyone who find it useful.
The technique of mixing, I learnt is called the macaroner. So happy macaroner-ing!
