Amaretto is an almond-flavoured Italian liqueur. Disaronno, the liqueur company that came up with this aromatic marzipan beverage, claim the recipe is unchanged since its secret formula was developed in 1525. The recipe includes burnt sugar, fruit and herb essences soaked in apricot kernel oil. Production remains in Saronno, a commune of Lombardy, but the beverage is distributed worldwide. It is a popular after dinner drink served with or without ice and goes particularly well with coffee. According to the Disaronno website, their amaretto is nut-free and is therefore safely consumed by people with nut or related allergies.
