These delicious almond-flavored biscotti have an ancient history, as they were supposedly first made during the Middle Ages. Their name is derived from the Italian amaro, meaning bitter, in reference to the sharp flavor of bitter almonds or apricot kernels, which are traditionally used in the recipe, together with egg whites and sugar.
They can be made either dry and crispy, or soft and chewy—secchi or morbidi, respectively—though amaretti are today synonymous with the crispy amaretti di Saronno from the homonymous Lombardian town, commercialized by Lazzaroni family and often referred to as the original amaretti.
Piedmont’s version, amaretti di Mombaruzzo are also crunchy and made exclusively with sugar, egg whites, sweet almonds, and apricot kernels, while the small town of Sassello in Liguria is renowned for their round-shaped, very soft and chewy amaretti, with almost marzipan-like interior, due to a very high percentage of almonds in the dough.
Lombardy's version, amaretti di Gallarate, are also very soft, but irregularly shaped, while amaretti Casperiani - from the province of Rieti - are made with hazelnuts instead of almonds. Amaretti di Carmigiano, also known as amaretti di Fochi, can be found in Tuscany - they are soft, imperfectly shaped, and smaller than the others, with characteristical amber color and strong almond aroma.
