Measure out the chia seeds and add to your grinding appliance. For small batches, a spice grinder or mini food processor is perfect. For larger batches, use a regular blender or food processor.

Pulse in short intervals, stopping to stir or redistribute the seeds often. Continue pulsing and grinding until a fine, flour-like powder forms. Be careful not to overblend or the oils will release and it will become paste-like.

Transfer the freshly ground chia powder to an airtight container. A mason jar or small Tupperware works well.
