A more modern variation, such as this Feeling Blue, got increasingly popular over time. Sugar was added to balance the flavours, and then the egg white component was added for a creamy finish and crisp foam. There are a few crucial factors to the perfect Feeling Blue for dinners and relaxing after a long day. Shake the egg whites twice to fully emulsify them for a beautiful smooth finish. When egg white drinks sit for too long, they might develop a faint sulphur odour without aromatics. To keep the drink fresher for longer, always serve it with bitters or garnish it with citrus. That's all!  Now go get a tall glass of Feeling Blue and beat those blues.
