These Italian amaretti biscuits are traditionally very crunchy on the outside and chewy and a bit marzipany in the middle. They are really easy to make and are gluten and dairy free. I love adore pistachios and I serve them with coffee at the end of a meal instead of making a dessert, or after dessert. They are dense and rich and you only need a couple. Perfect at Christmas and you can give them as gifts in little bags tied with a ribbon.
