This was Sara’s Christmas Negroni at the Good Spirits Co. Christmas Cocktail Club in Glasgow. She used house Bitters which are amazing and available to buy at the store in Glasgow but some combination of orange bitters and cranberry bitters would work.
40ml Illicit Gin
20ml Orange Colombo
15ml Nardini Amaro
7.5ml Orange & Cinnamon syrup
2 dashes spiced cranberry & orange bitters
Add all ingredients to an ice filled mixing glass and stir. Strain into an ice filled rocks glass and garnish with a dried orange slice.
