I'm a sucker for a Moscow mule, so a frozen London Mule Slush with gin instead of vodka was an easy sell to myself. The diet ginger beer brings the spice, the lime keeps it sharp, and a couple dashes of Angostura give it that grown-up bitter edge that stops it tasting like a soda. Out of the Ninja Slushi it's slushy and crisp, exactly what you want on a hot porch evening. Since the ginger beer is diet, add a splash of simple syrup so it actually freezes; sugar is what gives a slush its body. Adults only.
Your machine size
Slushi 64 oz (Standard) · quantities scaled ×1
⚠️ May be too boozy to freeze
Estimated 36.9% ABV is above the ~16% ceiling. Add water or juice to bring it down and restart the freeze.
⚠️ Over the hard-spirit limit
~24.0 oz of 40% spirit exceeds the ~4.1 oz max for this batch size. Dilute or scale down the liquor.
Ingredients
- Gin (44% Abv)6 oz
- Lime Juice2 oz
- Diet Ginger Beer18 oz
- Angostura Bitters6 dashes
Makes ~26 oz · est. 36.9% ABV
Directions
- 1Pre-chill the gin and diet ginger beer before preparation.
- 2Whisk the gin, fresh lime juice, and bitters in a pitcher, then slowly pour in the diet ginger beer.
- 3Pour the mixture into the Slushi vessel, close the lid, and select the SPIKED SLUSH setting.
- 4Allow the machine to run for 30 minutes until a smooth, scoopable texture is achieved, then dispense.
Tips
- Pour your liquid base at room temperature directly into the Slushi bowl, not chilled or pre-made ahead of time.
- The machine works best when you keep the base around 44% ABV gin as written; too much alcohol slows the freeze time.
- Check texture around the 30-minute mark by looking through the bowl; it should be moving from liquid to slushy, then fully frozen by 45-60 minutes.
Variations
- Swap the diet ginger beer for regular ginger beer if you want a sweeter, less sharp citrus profile.
- Use vodka instead of gin for a cleaner, more neutral London Mule Slush without the botanical notes.
- Add a half ounce of fresh ginger syrup to the lime juice before pouring for deeper ginger flavor without watering down the booze.
FAQ
- Can I use fresh lime juice that I made days ago?
- Yes, fresh squeezed lime juice keeps in the fridge for 3 to 4 days and works just fine. Just make sure it's still cold when you pour it into the machine.
- Why is my drink still mostly liquid after 45 minutes?
- The bowl may not be cold enough; run the machine for 5 more minutes and check again. If your gin is much higher than 44% ABV, it will freeze slower because alcohol has a lower freezing point than water.
- Can I make this without alcohol or with less gin?
- You can reduce the gin by an ounce, but the drink will freeze faster and taste sweeter since ginger beer is already sugary. Removing alcohol entirely makes it freeze quickly but loses the London Mule character.
- Can I store the slush in my freezer once it's made?
- It's best served fresh from the tap while it has that perfect slushy texture. If you store it, it will freeze solid and separate; thaw it and rerun the machine briefly to restore texture.
