Frozen Amaretto Sour

My dad's old-school amaretto sour is what got me messing around with this Frozen Amaretto Sour in the Ninja Slushi. Amaretto, a little bourbon, lemon, and simple syrup come out slushy and smooth, that almond-and-citrus flavor with a sour bite that keeps it from being dessert. He took a sip, raised an eyebrow, and said it was better than the bar, which from him is a medal. Adults only here. The bourbon is what stops it from getting cloying, so don't leave it out, because amaretto alone goes sweet fast.

Tips

  • Pour your liquid base into the Slushi bowl at room temperature, not chilled, since the machine does the freezing work for you.
  • If the drink isn't reaching slush consistency after 45 minutes, make sure your bowl was pre-chilled in the freezer before adding liquid, and check that the tap dispenser moves freely.
  • Scoop from the tap with a sturdy spoon or use the cup dispenser to catch the slush, working quickly before it starts to separate back into liquid.

Variations

  • Swap bourbon for rye whiskey for a spicier, drier edge to the amaretto and lemon balance.
  • Add a half ounce of fresh lime juice alongside the lemon juice to brighten the sour profile and add complexity.
  • Use orgeat syrup instead of simple syrup for a nuttier, deeper almond flavor that complements the amaretto.

FAQ

Can I use bottled lemon juice instead of fresh?
Fresh lemon juice gives better flavor, but bottled works if that is what you have on hand. The Slushi machine will still freeze it properly either way.
Why isn't my drink getting slushy after 30 minutes?
Check that your Slushi bowl was frozen solid before you poured in the liquid base. If the bowl wasn't cold enough, it takes longer to reach slush texture. Also make sure the machine is plugged in and the motor is running as it churns.
Can I make this less strong or alcohol-free?
Yes, reduce the bourbon and amaretto by half and add more simple syrup and lemon juice to keep the balance sweet and sour. For a non-alcoholic version, skip both spirits and increase the simple syrup and lemon juice to taste.
How long does the finished slush stay good in the Slushi bowl?
Enjoy it fresh right out of the tap while it is still slushy, ideally within 20 minutes of it finishing the churn cycle. If you leave it sitting in the bowl, it will start to separate back into liquid.
