The overall level of cooking is mostly defined by how long you use it—how many draws you take. You can get just about any type of final output you want. It is possible, for example, to bring the load to an even dark chocolate brown if you want to, although the taste towards the end may not be the best. Normally, we expect a single loading to provide between 4 and 8 draws, each of around 20 seconds in length. The key is to turn, tumble, and tap the Box to stir the load from time to time—this ensures even and consistent results.
Throughout the process, the ultimate taste is dependent on technique. Good usage technique with the Box consists of two aspects: control of the heating process and stirring of the material. Good taste begins by ensuring that the battery is only fully in the Box during a draw, and by controlling the draw rate. From the time that you put the battery fully in until you begin drawing should be fairly short—less than 5 seconds. To run the Box cooler (better taste), try drawing a little more quickly and do not wait as long before beginning your draw. To get more or denser vapor, draw more slowly or wait a little longer. The correct timing and draw rate—not too fast nor too slow—is something learned in time. When you complete the draw, be sure to pull the battery out a bit right away so that the Box does not continue needlessly heating (otherwise the load will get too hot and the taste will be changed).
Don't forget to shake! It's helpful to look through the cover to see that the stir is actually happening—sometimes bits stick together and do not mix as much as needed. Taste is improved by ensuring an even mixing by shaking the Box between draws.
