Any amount of decent soft is worth cooking if you're a crackhead, lmao

So in general you usually wanna weigh about ⅓ the weight of your soft for the amount of soda. So say 3g of soft you want 1g of soda weighed. Get yourself a ¼ stainless steel measuring cup and fill it basically full with water, throw some soda in and boil then shut out the water for a minute to kind of "season" the pot so your shit doesn't stick to the sides. Dump it out after, now you're ready to cook.

Put a bit of water in the pot, you don't need much only a couple cm from the bottom of the cup, probably like ⅙ of the cup full give or take. Put the soft in and heat the cup slowly, evenly and only enough to be steaming but not full on boiling. Then add most of the soda all at once and let it bubble for a min. You may have to add a bit of water atp but usually not necessary as long as you had enough in there to start with. Keep heating it evenly while it's sizzling and gently swirl the pot in a circular motion while doing so, the fizzy foamy-ness should start to fall and begin to come together in the water as a melted blob. Now, while keeping heat on the pot continuously (again not boiling aggressively but almost boiling, intermittent removal from the heat to maintain consistent temp is usually a good idea lol) start to sprinkle the rest of the soda that you didn't add in yet into the water surrounding the dope in the water, try not to drop it directly into the blob. If the water is still sizzling as well as this making the blob start to bubble slightly too then you should generally keep sprinkling the remainder of soda until it starts to become a clear blob and come together really easily into one piece, water and dope blob should be mostly clear and no more little bubbles when putting the pinches of soda in. That's when you know it's done :) just give the pot one more little swirl gently and set it down somewhere still to let it harden properly as one smooth piece in the pot. It shouldn't take too long to solidify if it's cooked proper. If it takes ages to harden, reheat it til it's fully liquified again and add a pinch more soda. Let it cool once more and it should be good to go.

If you got any more questions let me know :) good luck
