Quince Apple Jam Gin Sour Cocktail

"Quince apple jam gin sour cocktail is a tart, fresh, fruity, floral and spicy gin cocktail that uses rustic quince apple jam as a sweetener and flavouring agent to balance tart lemon juice, finished with an orange twist garnish. Quince apple jam gin sour cocktail is inspired by Harry Craddock’s (1930) recipe in The Savoy Cocktail Book for a marmalade cocktail using gin, lemon juice, orange marmalade, finished with an orange twist. This style of drink using lemon as a souring agent has roots in a very old drink called the sour detailed by David Wondrich (2015: 115-119) in Imbibe – which could be made with brandy, rum, gin or whisky – the archetypal sour included a spirit, sugar and lemon with a garnish of a slice or orange and berries in season."
