Dried cured frozen product is the best to use. I have tried fresh / wet frozen product. I got less end product and taste was some what greenish.

Place the bags in a 5 gallon bucket, fill 3/4 full with cold water. Add cured dried frozen product then cover the product with a bag of crushed ice. Add more water until the water is a few inched from the top of the bucket. Let stand for about 30 minutes. Use a mixer to agitate the ice and product 20 to 30 minutes then let rest for 20 minutes. Then repeat until the ice is almost all melted. Remove the bags together carefully and rinse with cold water.

Use a spoon to scrape the bubble hash (crack hash) off the bags screen.
Place on a paper towel and press the water out of the bubble hash. Careful here if you press all the water out the bubble hash will stick to the paper towel. Put the pressed bubble hash in the freezer until ready to smoke.

The white strains tend to give a blonde color hash. The White Widow crack hash i make is very smooth, tasty and keeps me alert and awake. I prefer bubble hash over joints any day.
