all you need is a bottle of amaretto, two fresh lemons, and standard white sugar from any supermarket. first make a basic syrup by disolving equal parts sugar in warm water and let it cool down. for the actual drink, measure out 50ml amaretto liqueur, 25ml lemon juice, and 25ml of your prepared syrup. pour all three liquids directly into a tumbler glass over several ice cubes and simply stir everything together with a spoon for about fifteen seconds until chilled. finish it with a slice of lemon on the rim if you prefer. it is a very cheap and simple drink to prepare for guests.
