How to make your own fresh green vegetable powder at home that is low in oxalates and highest in nutrients.
Chop the vegetables coarsely.
Blanch on the stovetop in boiling water for 3 minutes.
Drain/discard the cooking water and immediately rinse the blanched greens in cool filtered water to prevent overcooking.
Drain the water again and pat dry gently with a clean, cotton dishtowel.
Thoroughly dry the greens in a dehydrator set to 95-105 °F / 35 - 40 °C (preferred method). If you don't have a dehydrator, you can use an oven set to "warm" that goes no higher than 150 °F/ 65 °C (check veggies every hour to avoid over drying).
Pulse dried greens in a food processor until desired powder consistency.
Refrigerate fresh green vegetable powder in a glass jar with tight lid.
Add a teaspoon to each serving of potatoes, eggs, smoothies and soups.
Use up within 2 weeks.
