Uses
Cuisine
Thimbleberry fruits are flatter and softer (more fragile) than raspberries, but similarly have many small seeds. Because the fruit is so soft, it does not pack or ship well, so thimbleberries are rarely cultivated commercially.
Wild thimbleberries can be eaten raw or dried (the water content of ripe thimbleberries is quite variable), and can be made into a jam
Jam is a type of fruit preserve.
Jam or Jammed may also refer to:
Other common meanings
