Place a small batch of dried berries in a spice grinder, coffee grinder, or small food processor. These all pulverize berries into a fine powder. Don’t overload machine or berries won’t grind properly.

Pulse berries in short bursts until reduced to a fine, fluffy powder. Scrape down sides as needed. Take care not to overheat during grinding.

To remove seeds and stems, pour powder through a small mesh sieve or strainer. Gently shake over a bowl to collect the filtered powder. Discard debris left behind.

Store freshly ground powder in an airtight container along with a desiccant pack to absorb excess moisture. Glass jars or vacuum sealed bags work well.
