Making a non-dairy cream from soaked cashews: To use flour or not? To boil the soaked cashews or not?

Howdy folks,

I'm interested in making a non-dairy substitute for milk and half-and-half for my cereal and coffee. I'm interested in using cashews, and I'm very familiar with the cashew milk recipes out there. I've made a cashew paste/cream in the past. I had a problem with having to chew my chai when I was done. Therefore, I was wondering:

• If I should boil the hell out of my cashew - like in a pressure cooker, and then puree it?
• If I could make a milk/cream with cashew flour instead?
• Also, how good is a cashew based milk substitute for coffee and tea?

bon appetit
