Tried this with quandong (native Australian peach/apricot but sourer). Used apricot liqueur instead of peach. Worked well with the apricot liqueur but perhaps didn’t have enough quandongs to really extract enough fruit flavour. My quandong tree doesn’t produce enough fruit as it is not really native to where I live in Western Australia. Still a good cocktail to try it in.
Great drink. Let the peach ripen to almost overripe and you can cut back on the syrup a bit. Also I’m going to kick up the bourbon to 1.75 oz. next time as I felt it got a little lost. Finally I didn’t have Creme de Peche, but had Abricot du Roussillon and Creme de Cassis. Both worked well. Patience required when straining!
