This popsicle is tart—not like the sweet, sticky stuff from the ice cream truck—so those with a sweet tooth may want to stir in some sugar. As far as other recipe divergences, while tempting, we caution against adding more amaretto to booze up the popsicle. Alcohol has a much colder freezing point than water, so your popsicle will be more like a slushy if there’s too much liquor. Instead, just eat more popsicles. Cheers!
