Biscotti refers to a long, hard, twice-baked Italian dipping cookie in various flavors including anise, chocolate, almond and hazelnut. It taste excellent dipped into espresso or dessert wine.
Biscotti are hard Italian biscuits traditionally made with hazelnuts and aniseed. Though modern variants include pistachio nuts, lemon and orange rind. They are so crunchy because they are cooked twice; hence the name, which derives from the Italian bis (twice) and cotti (cooked). As a result they remain hard even when dunked in liquids and are often served with coffee and dessert wines.
