My math is horrible … what would be 10.4 fluid ounces, 52 fluid ounces of water & 11.6 fluid ounces of light rum be closest in cups for the 74 oz fill line for the large batch …. I’m familiar with cups & ounces but when it’s not 1/4, 1/2, 3/4 that’s where my confusion lays
Totally fair question. You’re definitely not alone. Once measurements stop lining up neatly with ¼, ½, or ¾ cups, it gets confusing fast.
The good news is this recipe is very forgiving, so you don’t need exact conversions. Rounding is perfectly fine and won’t affect the final result.
Here are some easy cup estimates you can use:
• 10.4 fl oz is just over 1¼ cups
• 52 fl oz of water is about 6½ cups
• 11.6 fl oz of light rum is about 1½ cups
If you’re a little over or under, don’t worry. Frozen drink recipes like this have a lot of flexibility, and it’ll still slush and taste great.
How do you make a virgin one in the slushie do you add more water?
Replace the alcohol with water.
