Badder and budder are typically considered extracts because they are primarily made using liquid petroleum gases (LPG) such as butane and propane. As with other textures, the process involves a closed-loop system. The only difference is the post-extraction technique.
The consistency of the concentrate changes from shatter to budder when the extracts are whipped on a hot plate at roughly 100 degrees Fahrenheit (38 degrees Celsius) before being placed into a vacuum oven. The exact temperatures and amount of agitation required differ from strain to strain, but most budder is purged with a little heat and pressure for 24 to 72 hours.
