Put the ice in before topping with soda

Use the two glasses with the planned ice already divided between them. Mix cranberry juice cocktail and fresh lime separately so each glass receives the same base, then add the soda slowly. The ingredient is cranberry juice cocktail; another cranberry product may give a different sweetness, even when its color looks similar.

Keep the one gentle stir after topping so the drink mixes without repeated agitation. Finish with a lime slice and serve promptly. A glass filled with the full ice and liquid needs practical headroom for carrying, so choose a larger glass if your cubes take more space than expected. Keep another round’s soda sealed and chilled until it is needed.
