1 c. regular orange juice
2 c. calamondin pulp
1 tbsp. baking soda
Water
3 c. sugar

Wash fruit in kettle with baking soda. Cover with boiling water and let stand 10 minutes. Wash well with cold water several times. Quarter fruit and remove seeds. Chop fruit in blender. Combine with juice and sugar. Bring to a rapid boil, and boil for 10 to 15 minutes. I use 12 minutes, because I prefer the jam to be not too firm.
