What each ingredient does

White sugar: Provides sweetness and body to the syrup.
Tartaric acid: Adds acidity that gives the nectar its tart, sharp bite.
Egg whites: Whipped whites add a light, foamy texture to the mixture.
Soda: Releases carbon dioxide bubbles when added, making the drink effervesce.
