Place 1 pound of lentils into a fine-meshed sieve or colander and rinse the lentils thoroughly under cold water. Remove any debris or discolored lentils.
Lay a dish towel on a large baking sheet and spread the rinsed lentils over the towel in a single layer. Pat the lentils with another towel to remove excess liquid. Let the lentils sit until they are completely dry.
Once the lentils are completely dry, place the lentils in a large skillet and toast them over medium heat for approximately 5 minutes. Stir frequently to prevent the lentils from burning. Remove the lentils from heat and let the lentils cool completely.
Attach the Mockmill Grain Mill to your KitchenAid mixer. Set it to the finest setting. Place your toasted lentils in the mmm. Turn on the mixer and grind the lentils.
Sift the lentil flour through a fine sieve into a bowl or container. You can send any pieces of lentils that are too large to pass through the sieve back through the grinder.
Store the lentil flour in a sealed container.
