My strongest memory of cumquats is as a child at my Grandparents holiday house in Merimbula.
I found these cumquats ripe for the picking in my parents garden. The sweetness of bananas vs sour / bitterness of cumquats vs rosemary worked really well
What I threw in
1 banana (frozen overnight)
3 cumquats, peeled
1 tspn fresh rosemary
Throw all ingredients in blender – depending on what consistency you like, you can slowly add about 1/4 cup of water or coconut water
