Portable ways to daily grind & powder/ paste 8-9 overnight soaked & peeled Almonds while traveling?
Use a small mortar and pestle, so you're not dependent on electric outlets, batteries or such. With this small amount, the required manual effort is very low, and you can use a very small mortar and pestle, so you can pack light. Also, you can soak the almonds in the mortar itself. And it is also possible to add other ingredients directly to the mortar after the pressing is done. 

You will end up with a paste rather than ground almond flour, but I don't think you can get almond flour with soaked almonds in a food processor or a mill either.
