Cavendish from Bolivia Criollo Black
I stemmed a very large string (~46 leaves) of Bolivia Criollo Black mid-to-upper leaf that had fully color-cured. This was compressed by hand to fit into the bottom half of a 1 gallon Ziplock, and rested overnight (to hold the compressed shape).
Using a large
pressure cooker, with a tower of jury-rigged metal stacked inside, topped by a perforated pizza tin, I placed the compressed mass of leaf so that it was held completely away from the 4 cups of water contained in the cooker. It was sealed and brought up to pressure, so that the weight rocked gently.
I set a timer for 2 hours. This process fills the house with a potent (not unpleasant) aroma of cooking leaf. After each 2 hours, I turned off the heat, vented the pressure, opened the cooker, added 4 more cups of water, and loosely rearranged the soggy pile of leaf, in order to expose as much of the leaf to the direct moisture as possible. The cooker was then resealed and brought back up to pressure with heat. This was repeated for a
total cooking time of 6 hours.
The wet leaf was then removed, gently teased apart, and piled onto a baking sheet that had been lined with aluminum foil. I will leave it to dry-down until it can be easily formed into roll-cake, and sliced. The slices will then be dried in the oven at 150ºF for 10 minute intervals, until the shred can be bagged.
Freshly made Cavendish is very slow to dry, and will easily mold if not taken down to low case before storage.
I was pleased with the dark color. This batch turned out uniformly darker than previous batches. I do believe that direct exposure to the steam moisture within the pressure cooker is necessary to get that dark color.
