Hi,
On the Great British Baking Show, they had to bake a dessert without sugar. They could use honey, agave, molasses and such.
The Muslim woman made a low calorie 'jam' by pureeing blueberries and mixing in basil seeds for jam texture. She said the seed bloom upon contact with liquid. I have had beverages with basil seeds, which has a viscous quality. It never occurred to me to use it to replicate a jam mouth feel.
The judges loved her cake and this jam.
Regards,
