Take 5 layers of paper towel. Place wet blob on paper towel stack. Fold over paper towel so material is in between. Press with heel of hand. A lot of water will get pushed out of blob and get wicked into upper and lower towel stack. Do this quickly or the paper towel will stick to hash. If done quickly(5 or 6,7 seconds) , you can peel off the paper towel cleanly leaving you a semi dry puck. If the flattened puck is still wet i will do it again with fresh stack of paper towels. Usually one press in towels is enough. 2nd attempt usually is too sticky. Take flattened puck of hash and put on parchment paper. Do not use wax paper. Put puck on patchment in a warm 80F area with good air flow of for 4 or more days until dried throughout puck. I put it under grow light for this. Dont rush this and dont play with puck for at least 2 days or it will just stick to your fingers. When it really starts to dry, it will not stick to you or the parchment. Once i think it completely dry, i vacuum seal and store in freezer. If ever you get in trouble, and you get a sticky mess, put hash in freezer for 20 min. It will cool down enough so you can touch it without sticking. Better to make pucks about 2 to 4 inches in diameter. If too big and thick, the pucks dont dry well in the center.
Just my 2 centavos. Hope it helps.
