A fresh Gin Sour cocktail, as seen in a Danish newspaper:
2 egg whites
4cl Simple Syrup
10 cl Gin
6 cl Freshly Squeezed lemon juice
Pour all ingredients into a shaker. Shake for a long time without ice – Really hard. The foam is important for this cocktail. When done with first round, ad ice and go for round two. Pour through a strainer into a glas.
