Below is the method for making nut powder, plus links to my favorite recipes that include nuts, nut butters, and seeds. Nutrition will vary depending on how much you use. Info here is per tablespoon.
Add the nuts to a blender. Secure on the lid and grind, starting on low and working up to high. Grind to form a powder (the time it take will vary on the nut and its firmness), but before it turns into nut butter. You will be able to visually tell when it's a powder.
Store in an airtight container in a cool dry place or in the fridge for up to 3 months. You can also freeze for up to 6 months.
Sprinkle over veggies, grains, meat, oatmeal, banana slices, or any other food that sounds good to you!
Notes
You can serve the nut powder from about 7/8 months and up.
Roasted cashews may also work.
You can also serve nuts safely in:
Peanut Puree (either on a spoon or stirred into oatmeal)
Peanut Butter Toast: Lightly toast bread and add a thin layer of nut or seed butter.
