Hello Sara,
1. Yes you can use that (Tianshan) April Mist instead, in case you do not want that jasmine aroma. April Mist is actually a very good choice for its gentleness to not fight with the other ingredients.
2. You can use raisin but the TCM effect will not be the same. Tastewise, I think the gentler wolfberries are also more suitable for the job. If you want fruits etc in the jelly, cut some peeled and seeded grapes, peaches, mandarin oranges, cherries etc. However, they do not deliver the kind of TCM complementary effects wolfberries do
3. Another great sugar to use other than raw sugar is rock sugar, which sweetness is such that there is no dryness aftertaste as brown sugar or white sugar have. To use rock sugar for the recipe, please dissolve it by simmering in 250 ml of water. Don’t forget to deduct this amount of liquid from the total liquid amount. The good thing about rock sugar over raw is that it can sustain a bit more of boiling and stirring without turning sour.
4. Most certainly. Also calculate the total liquid volume when you do. Mind that you do need liquid in steeping the tea and dissolving the konjac powder
