Rinse the woflberries then soak them in a bowl of hot water.
Remove any hard and dark bits (leaves/ twigs) from the osmanthus flowers.
Heat 1 litre of water in a pot. Whilst the water is heating, you may want to rinse the osmanthus flowers in a sieve. (This is an optional step as it removes dust but the wet flowers are difficult to get off the sieve!) When the water is almost boiling, add all the osmanthus flowers to the water. Let the osmanthus tea simmer for 5 minutes.
Whilst the pot is simmering, mix the white sugar and konynyaku powder thoroughly. (Skip this step if using honey or rock sugar.)
After 5 minutes, quickly add the konnyaku powder- sugar mixture (from the previous step) to the pot whilst whisking continuously. Bring the pot back to a boil before reducing the heat to a simmer. Whisk continuously and simmer for 3-4 minutes to get rid of any lumps. (This ensures that the jelly does not turn back into water after setting and that you don't have a lumpy jelly.)
After the 3-4 minutes, add the goji berries. Do not pour the soaking water into the pot or it will affect the setting of the jelly- you can keep it for tea, stews or soups. Continue to simmer for 3 minutes.
Pour the jelly into molds and allow to cool. Stir with a toothpick to ensure that the tea and wolfberries are dispersed evenly througout the jelly. When not too hot (you don't want to raise the temperature of your fridge), transfer to fridge to set for at least 3 hours (I usually leave it overnight)
Alternatively: if you don't have fancy molds, just pour the jelly into a wide and shallow heat-proof container to set, then cut with a sharp knife or cookie cutters.
