How to Crush Flax Seeds

Grind the seeds in a coffee grinder. Place the seeds in the grinder and run, stopping when the flax is a fine powder. Use in baked goods such as muffins and pancakes. If a more crunchy texture is desired, such as for use in yogurt or on top of breads, grind for a shorter period of time.

Crush the flax seeds with a mortar and pestle. Place about 1 tbsp. of seeds at a time into a mortar and crush it with a pestle. Press down on the seeds, and against the bottom and sides of the mortar. This produces a less fine texture than a coffee grinder, and it's difficult to crush the seeds evenly.

Place the seeds in a plastic bag and roll over with a rolling pin. Empty seeds into a sealable sandwich bag to prevent the loss of seeds. Lay the bag of seeds flat on a surface and use the rolling pin to crush the seeds. If the flax seeds prove too small to be crushed as finely as desired, use a spoon instead of a rolling pin. Press the back side of the spoon against the plastic bag by using the heel of one hand. Press systematically outside the surface of the bag to make sure all of the seeds are crushed evenly.
