When you add alcohol like spiced rum and limoncello to a dessert, it doesn't only layer on more flavor, but it also intensifies the ones that are present.
Amaretto, which literally translates to “little bitter” in Italian, can be used as a substitute for vanilla extract or added to cookies and cakes for an extra boost of flavor.
If you’re using it in place of vanilla extract, all you need to do is swap out an equal amount, and your dessert will have a perfectly balanced flavor.
