Leave room for the foam

Set out the glasses before opening the soda. Each drink starts with 60 milliliters pineapple juice and 120 milliliters soda, followed by 1/4 cup sherbet. The glass needs extra space because the cold sherbet makes the fizzy mixture foam. A glass filled to the top before the sherbet goes in is likely to overflow.

Pour the soda slowly and add the sherbet gently. If the foam rises quickly, pause and let it settle before moving the glass. A tray beneath the four glasses catches a small spill and makes cleanup easier. The froth is the decoration; the drink does not need dry ice or non-food props.

Choose sherbet by its label

Lime sherbet supplies both flavor and the pale green color. Its shade varies by product, so expect a soft lime color rather than an intense neon effect. Sherbet can contain milk; it is not interchangeable with a dairy-free label. Keep the carton available for anyone checking ingredients.

Do not add food coloring simply to chase an illustration. If the color is subtle, clear glasses and a dark serving tray can make the existing drink easier to see without changing its flavor. Use well-chilled juice and soda so the sherbet does not melt immediately.

Serve one round at a time

For two drinks, halve the recipe: 1/2 cup juice, 1 cup soda and 1/2 cup sherbet in total. For eight, double the ingredients and use eight glasses, or a punch bowl with generous headroom. Keep the serving proportions the same.

Advance preparation means chilling the drinks and setting out the equipment, not combining everything early. Add soda and sherbet just before serving and keep unused sherbet frozen. The finished mixture loses its frothy texture as it stands, so make a fresh small round when another is wanted.
