Preheat the oven to 400 degrees F.
Boil 2 cups of water (I just heat up water in my tea kettle). Pour the water over the cashews and let soak for 5 minutes or up to an hour.
Drain the cashews, discard the soaking water and add them to a high powered blender along with the 2 1/2 cups fresh water, lemon juice, white miso paste, salt and tapioca starch. Blend until very smooth.
Pour the watery mixture into a medium saucepan (preferable oven safe). Bring the heat to medium-high and start stirring with a large spoon or spatula.
After a few minutes, it will start to get clumpy. Keep stirring constantly, and suddenly it will become super gooey, stretchy and thick. As soon as this happens remove the pan from heat.
If using an oven safe pan, pour the pepper jelly over the top of the cheese. If not, transfer the cheese to an oven safe dish to fit, then pour the pepper jelly over it.
Bake in the center rack of the oven for 10 minutes, uncovered.
Once baked, put a lid on it to keep the cheese warm until ready to serve. Serve warm with pretzels or crackers for dipping. Enjoy!
