Calamondin Orange Marmalade Recipes

My friend Roxanne has a glorious Seville Calamondin Orange tree in her yard in Tujunga.
Our schedules aligned perfectly yesterday, and we were able to spend an evening together, experimenting with marmalade recipes.

We started with this basic recipe :

Bring to boil, cover, boil gently 25 min
