Make protein powder at home with just one ingredient and 15 minutes. It's naturally vegan, allergen friendly, and great to add to smoothies, baked goods, and sauces. You can even customize it with additional flavors if desired.
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.
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.
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.
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.
You can customize it by adding additional protein and flavor options. See the above article for suggestions and measurements, plus an example and how I used it in a smoothie.
