My mother's recipe (recipe 80 years old, and now mine) -always boil the seed pods up separately. Strain through fine muslin and add liquid to the red pods and sugar. No lemon is used, as it changes the real rosella flavour.

Coastal actually. Planting seeds before the ground has warmed up is frustrating. If you buy seeds, try planting early if you are keen. Some will do okay. Others will sit there and laugh at you before shrivelling. Simply plant another seed. In cool climates it is often pot luck, but they will eventually take off. They will survive and fruit well into autumn, especially in areas where there are no frosts. Pick them in flower daily and put them in the fridge until you have enough. Then boil them gently with a bit of sugar and progressively freeze them. At the end of the season thaw them out and make the jam. Patience is a virtue.
