Common Mistakes to Avoid
- Using warm root beer – it will melt the ice cream too quickly and dilute flavor.
- Over‑filling the glass – the foam can overflow, creating a messy presentation.
- Choosing a high‑proof spirit – it can overpower the delicate vanilla notes.
- Skipping the gentle stir – without it the alcohol may settle at the bottom, leaving an uneven taste.
Storing Tips for the Recipe
- If you need to prep ahead, keep the ice cream and spirit separate in the freezer and refrigerator, then combine just before serving.
- Store any leftover root beer in a sealed container in the fridge to maintain carbonation.
- Avoid refreezing the float once it has melted; the texture will become grainy.
