It's even better if you grind it yourself. I use the golden flax (just because I prefer the taste). I keep the flax seeds in the freezer. Then I grind enough, in a coffee grinder, to fill a small ziploc disposable container (which I also keep in the freezer). This will last me a few days unless I am using a lot for a recipe.

The already ground flax is very handy, especially if you are using a lot, but I, personally, think that the taste of freshly ground is superior.
