The grapefruit juice plays an integral role in your Paloma's taste and quality. Freshly squeezed grapefruit juice is ideal for a bright and fresh taste. If fresh juice is not available, opt for high-quality, pure grapefruit juice with no added sugars or artificial flavors. Note that you can use either pink or white grapefruit juice; as there are subtle differences in their tastes, experiment to see which you prefer.
