Ninja Slushi Lemon Drop Ingredients
- Lemonade
- Vodka
- Triple Sec or Cointreau Liqueur: The sweetness and citrus notes complement the vodka, but it's optional since the lemonade provides plenty of sweetness.
- Lemon Juice

Can I Make This With a Regular Blender
Yes, but you will need to add a lot of ice to get that thick texture, which may cause you to adjust the ratio of lemonade and/or lemon juice. You will have to adjust to taste and what works for you.
How to Fix Error Messages Related to Alcohol
If you’ve ever tried whipping up a margarita, piña colada, or any frozen cocktail in your Ninja Slushi machine and ended up staring at an error message, or worse, a sad, watery mess. Trust me, I’ve been there. I went through all the trial and error so you don’t have to. Here’s the real reason it happens (and how to fix it).
- Alcohol and Freezing Don’t Mix Well – Alcohol doesn’t freeze like water, so if your drink is too strong, the machine can’t do its job. Too much liquor = no slush. The machine will either skip the shave or refuse to dispense altogether.
- Your Ratios Are Off – The Ninja Slushi needs balance. You’ve got to have the right mix of alcohol and water-based liquid. Too little liquid, and you’ll be scraping ice chunks. Too much, and it’ll pour out like a cocktail instead of a slushie.
- Thick Mixers Can Mess Things Up – Heavy juices, creamy ingredients, or thick syrups can slow the machine down and make your texture clumpy or uneven. Go lighter with those or mix them in after blending.
- Don’t Overfill It – There’s a reason the machine has fill lines, y’all. If you go over that max line, it’s going to struggle to freeze and dispense properly. Keep it in range for the perfect slush every time.
How to Make Cocktails Without Any Errors in the Ninja Slushi Machine
If your drink is too boozy, the Ninja Slushi machine is gonna let you know. You’ll see the temperature lights start flashing one by one from the bottom up, the preset buttons blinking like crazy, and then it’ll start beeping at you every minute for 15 minutes. That’s your cue to cool it on the alcohol and add a splash of something lighter like water or sparkling water to balance things out.
- Keep It at 1–1.5 oz Alcohol per Serving – Anything more, and your drink won’t freeze up right.
- Add a Little Extra Liquid – Water, juice, or mixer helps it blend smooth and thick instead of icy or runny.
- Start with Cold Ingredients – Pre-chilled liquids help the mix freeze faster and stay slushy longer.
- Go Easy on Thick Syrups or Creamy Stuff – If you use them, thin them out with water or juice so the machine doesn’t struggle.
- Respect the Fill Line (64 oz Max) – Overfilling just throws everything off. Stay in that sweet spot for the perfect pour every time.

Taste before adding it to the Ninja Slushi. If it’s too tart, add simple syrup or sugar. Remember: slushies taste less sweet when frozen.
Most batches take 20–45 minutes depending on your machine and how cold your ingredients are. Using chilled ingredients speeds it up. It took me 25 minutes.
