Dilute teaspoonful of apricot jam in a glass of Abricotine. Add a teaspoonful of Peach Bitters, slightly less than 2 glasses of Gin and two and a half glasses of French Vermouth. Place this mixture in a shaker and put it on the ice to cool. When quite cold pour in two or three glasses of crushed ice and shake well. Strain into a cocktail glass.
