Batch Notes

I made a coffee butter starting with 11 ounces of coconut oil, 4 ounces shea butter, and 4 ounces of cocoa butter. I heated the oils until the oils flowed smoothly (being careful not to scorch the oils) and simmered in 100 grams of medium ground Colombian coffee for 8 hours. Afterwards I strained the oil through a coffee filter to remove the used coffee grounds. The oiled flowed smoothly through the coffee filter when it was hot. The smell of the shea butter and cocoa butter with the coffee smelled like a rich mocha coffee. Of the 19 ounces of oil, I seemed to have lost 17% of the original oils (leaving me with 15.77 ounces of the coffee butter). I adjusted the final recipe accordingly to bring the batch to 32 ounces by assuming that I had 83% of each oil originally used to create the coffee butter, that is a final 3.32 ounces of cocoa butter, 3.32 ounces of shea butter, and 9.13 ounces of coconut oil.

If I had enough coffee butter I would have formulated this recipe as 1 ounce castor oil, 12 ounces olive oil, and a 4/4/11 blend of cocoa butter, shea butter, and coconut oil brewed in coffee to make a coffee butter.
