Step 1

Place peas in a blender or food processor. I use a Ninja blender but any high-speed blender or food processor will do. Make sure whatever appliance you use is completely dry. You do not want any moisture in it or you will end up with a paste instead of a flour. Blend for around 3 minutes. Make sure any openings are covered while it's running so you don't have pea flour wafting out of it.

Step 2

Sift the processed peas over a bowl with a sieve or mesh strainer to separate the powder from any of the larger pieces. Reprocess the large pieces in your blender or food processor for another 3 minutes and sift again.

Step 3

Any leftover larger pieces can be ground using a coffee or spice grinder, or throw into a soup or stew so they don't go to waste. They're so small that they should cook quickly.

Step 4

Store pea protein powder in an airtight container in the refrigerator for up to a week or freeze for longer. See above article for how to add additional protein and flavor options to the powder.
