Finely Ground Brown Flax Seed. Can be used as a baking flour or topping in yogurt and cereal.
When using it in a recipe, use it in limited quantities, and boost liquid by 1 tablespoon for every 3 tablespoons of flax flour used, because flax is very water-absorbent.
The gummy properties of the fibre in the seed can help improve bread loaf volume a bit, if other compensations are also used. You can swap in up to 15% flax flour in a bread recipe, but you may wish to increase yeast a bit, up to about 25% more if you've swapped in 15% flax flour.
Store ground flax at room temperature for up to 4 months. Longer if sealed & refridgerated. Does not keep as long as flax seeds.
