RE: Clementine & Ginger jam with a twist of Rooibos Tea

This is my favorite berry for jam. It has a deep rich flavour. I don't know if they exist outside Canada, perhaps under a different name.

The saskatoon (Amelanchier alnifolia) is a small to large shrub, or small tree, which belongs to the Rose family. It is closely related to the apple, hawthorn and mountain ash. The saskatoon is a perennial, woody, fruit bearing shrub which is capable to adapting to a wide range of soils and climatic conditions. The saskatoon is native to the Canadian Prairies, the Northwest Territories, the Yukon, Alaska, British Columbia and the northwestern and north central United States. The saskatoon is hardy to -50º to -60º C. Flowering occurs in early May to early June.

The saskatoon was an important food source for both indigenous peoples and the early pioneers. The saskatoon is also an important food source for wildlife during the winter season. The saskatoon was also used as a source wood and as a medicinal plant. Today saskatoons are used in a wide variety of ways from pies, jams, jellies, syrups ice cream toppings, wine, liqueurs and flavour concentrates to components of baked goods. They may be used fresh or frozen and can be dried to yield "raisins" or fruit leathers.
