What it is
Flaxseed (linseed) is small, flat, glossy seeds, brown or golden. Whole seeds often pass through undigested, so they are usually ground; ground flax mixed with water forms a sticky gel that binds batters like egg. It has a mild, nutty, slightly earthy flavour and turns rancid quickly once ground.
