Egg

Eggs are used to add viscosity and mouthfeel to cocktails, sour cocktails like Whisky Sour, tastes the best when made with added egg white. Egg whites create a creamy texture and a thick layer of foam on top of a cocktail. While unlike using just the white, adding the yolk adds a bit of a flavour to the drink, it helps emulsify the other ingredients and adds the eggnog flavour to your cocktail.
To get the silk smooth texture and mouthfeel and the foamy head without weakening the drink by melting the ice from too long shaking, which is needed to break the proteins of the egg white to froth up, dry shake the ingredients first, that is, pour all ingredients and the egg white in your shaker and shake hard without ice first, for about a minute and then add ice and shake again.
