You'll recognize the sweet and bitter taste of amaretto before ever drinking it - it is used as a flavouring, especially for tiramisu. This bitter-almond liqueur is 25 percent alcohol and isn't only used to flavour desserts (biscuits, ices, panna cotta, etc. ); it is also enjoyed neat or with ice. It's the star ingredient in many cocktails, the most famous being the Amaretto Sour.
