Bubble gum syrup is a sugar syrup flavored to taste of bubble gum candy.
It is bought for the flavor, mostly for bright drinks with vodka, rum and citrus. It is also the sweetener, so if a recipe adds sugar syrup as well, use less of it.
Another bubble gum syrup
Monin or 1883 swap in at the same amount.
Homemade replacement
Mix two parts strawberry syrup with one part banana liqueur. Expect a little alcohol from the liqueur.
Bubble gum vodka
Far less sweet. In place of the syrup it adds strength and takes sugar away, so the drink needs a little sugar syrup.
Pink and blue syrups
The color comes from food dye. It changes how the drink looks, not how it tastes.
Sealed, it keeps for months in a cupboard. Once opened, keep it in the fridge, less for the syrup than for what the neck and the pourer carry into it.
