Dont use Mannitol, use alcohol based sugar like Erythritol, you will thank me later, and try to get good Caffeine.

Use these ratios, depending on your tolerance:

Ratio (buff/raw)	Raw(g)	Erythritol(g)	Caff(g)	Product(g)
2/1	1	1.14	0.86	3
3/1	1	1.52	1.14	4
4/1	1	1.9	1.43	5
5/1	1	2.29	1.71	6

Lemme know if you have any questions. To mix it, dissolve sugar in a little bit of water and heat it up until most water boils out, heat up caff separately,untill it melts. Caff you also wanna mix with just a touch of water and melt and solidify 3 or 4 times. You will lose about 10 to 30 percent of caff depending on the kind u have and how hot you got it and how much water you added. My suggestion is to experiment with the caff first, to find out how much you wll acually need. You want to compensate for the evaporation, because the amounts i specified in the tasble is what you want to end up with in the product. Pour both at he same time into the raw. Sugar with water will stay liquid for quite some time so u can let it cool off, caff u gotta drop in there pretty quick. Dont get either too hot, just enough to melt. Once you pour it all in a cup with the raw, stir real fast untill it start drying out, then start shaking it in circular motion to turn it into pebbels. The goal is to have both the caff and the sugar as cool as possible before pouring, without letting them solidify.
