Fountain Drink Recipe

Chill components

Place the carbonated water and syrup in the refrigerator for at least 30 minutes before mixing. Cold liquids hold carbonation better and produce a better fountain-drink texture.

Measure 1/2 cup of cola syrup into a chilled mixing pitcher or cup. This is a typical fountain-soda ratio; adjust to taste if you prefer sweeter or lighter flavor.

Slowly pour 2 cups of chilled carbonated water into the pitcher over the back of a spoon or down the inside wall of the pitcher to preserve as much carbonation as possible. Pour gently to minimize foaming.

Stir gently once with a long spoon or stirrer for 5–8 seconds to combine syrup and carbonated water. Avoid vigorous stirring which will flatten the drink.

Fill a 16–20 oz serving glass with about 1 cup of ice cubes (or to preferred level). If you prefer less dilution, use chilled glass and less ice.

Pour the mixed fountain drink over the ice, pouring slowly to avoid excessive foaming and spillage.

Garnish with an optional lemon slice on the rim and/or a maraschino cherry dropped into the glass.

Serve immediately with a straw. Recommend tasting and adjusting future mixes by increasing syrup in 1–2 tablespoon increments if a stronger flavor is desired.
