If your flax seeds aren’t already ground, grind them by placing them in a high speed blender or electric coffee grinder for a few minutes until finely ground.
In a small bowl, whisk together the flax seeds and water. Allow to stand for 15 minutes until it thickens, then give it another whisk. Use as a 1 for 1 replacement for eggs in baked goods like quick breads, muffins, cookies and pancakes.
