There's a lightweight, portable and inexpensive flax-seed grinder that most of us can readily use - teeth!
A tablespoon of nice fresh organic seeds, chewed for a half minute or so, will be mostly broken open to release their oil, nutrients and fibre in the most natural way. The taste is fine and it's good jaw exercise. A few seeds will escape, but with good mastication, only a few.
Ideal for when travelling, to combine with your favourite Budwig meal.
