Amaretto is a sweet Italian liqueur with a distinctive bitter-almond flavor. It originated in Saronno, where Disaronno and Lazzaroni are still made, but the style is now produced across Italy and beyond.
Crème de noyaux
Comes closest, with a similar marzipan taste. It is often red and will tint the drink.
Orgeat and brandy
Use equal parts to replace it in the same total amount. It gives a nuttier, more floral result, so taste and adjust.
Almond syrup
Alone, it brings the almond and sugar but no strength. The drink ends up weaker and sweeter.
Will not stand in. Both names come from the Italian for bitter, but a herbal liqueur cannot replace amaretto.
Sugar and alcohol both preserve it, so an opened bottle keeps for years. What fades is the almond aroma on top; the sweetness and the body stay where they were.
